Since this is intended to support _both_ groups and extras, it doesn't
make sense to just name it for groups. And since there isn't really a
word that encapsulates both "extra" and "group," we just fall back to
the super general "conflicts."
We'll rename the variables and other things in the next commit.
## Summary
I need this for the derivation chain work
(https://github.com/astral-sh/uv/issues/8962), but it just seems
generally useful. You can't always get a version from a `Dist` (it could
be URL-based!), but when we create a `ResolvedDist`, we _do_ know the
version (and not just the URL). This PR preserves it.
This PR adds support for conflicting extras. For example, consider
some optional dependencies like this:
```toml
[project.optional-dependencies]
project1 = ["numpy==1.26.3"]
project2 = ["numpy==1.26.4"]
```
These dependency specifications are not compatible with one another.
And if you ask uv to lock these, you'll get an unresolvable error.
With this PR, you can now add this to your `pyproject.toml` to get
around this:
```toml
[tool.uv]
conflicting-groups = [
[
{ package = "project", extra = "project1" },
{ package = "project", extra = "project2" },
],
]
```
This will make the universal resolver create additional forks
internally that keep the dependencies from the `project1` and
`project2` extras separate. And we make all of this work by reporting
an error at **install** time if one tries to install with two or more
extras that have been declared as conflicting. (If we didn't do this,
it would be possible to try and install two different versions of the
same package into the same environment.)
This PR does *not* add support for conflicting **groups**, but it is
intended to add support in a follow-up PR.
Closes#6981Fixes#8024
Ref #6729, Ref #6830
This should also hopefully unblock
https://github.com/dagster-io/dagster/pull/23814, but in my testing, I
did run into other problems (specifically, with `pywin`). But it does
resolve the problem with incompatible dependencies in two different
extras once you declare `test-airflow-1` and `test-airflow-2` as
conflicting for `dagster-airflow`.
NOTE: This PR doesn't make `conflicting-groups` public yet. And in a
follow-up PR, I plan to switch the name to `conflicts` instead of
`conflicting-groups`, since it will be able to accept conflicting extras
_and_ conflicting groups.
## Summary
We're inconsistent with these -- sometimes it's `Error::Fetch` and
sometimes it's `Error::Download`. The message says download, so let's
just use that?
## Summary
This got moved to `InstallTarget`! Must've been an oversight not to
delete. I verified that no code was changed here since the date that we
moved it to `InstallTarget`.
## Summary
Just as we don't enforce tag compliance, we shouldn't enforce
`--no-build` when validating the lockfile. If we end up building from
source, the distribution database will correctly error.
Closes https://github.com/astral-sh/uv/issues/9016.
## Summary
At time of writing, `markupsafe==3.0.2` exists on the PyTorch index, but
there's
only a single wheel:
`MarkupSafe-3.0.2-cp313-cp313-manylinux_2_17_x86_64.manylinux2014_x86_64.whl`
Meanwhile, there are a large number of wheels on PyPI for the same
version. If the
user is on Python 3.12, and we return the incompatible PyTorch wheel
without
considering the PyPI wheels, PubGrub will mark 3.0.2 as an incompatible
version,
even though there are compatible wheels on PyPI.
Closes https://github.com/astral-sh/uv/issues/8922.
## Summary
We were making some incorrect assumptions in the extra-merging code for
universal `pip compile`. This PR corrects those assumptions and adds a
bunch of additional tests.
Closes https://github.com/astral-sh/uv/issues/8915.
After https://github.com/astral-sh/uv/pull/8797, we have spec-compliant
handling for local version identifiers and can completely remove all the
special-casing around it.
Implement a full working version of local version semantics. The (AFAIA)
major move towards this was implemented in #2430. This added support
such that the version specifier `torch==2.1.0+cpu` would install
`torch@2.1.0+cpu` and consider `torch@2.1.0+cpu` a valid way to satisfy
the requirement `torch==2.1.0` in further dependency resolution.
In this feature, we more fully support local version semantics. Namely,
we now allow `torch==2.1.0` to install `torch@2.1.0+cpu` regardless of
whether `torch@2.1.0` (no local tag) actually exists.
We do this by adding an internal-only `Max` value to local versions that
compare greater to all other local versions. Then we can translate
`torch==2.1.0` into bounds: greater than 2.1.0 with no local tag and
less than 2.1.0 with the `Max` local tag.
Depends on https://github.com/astral-sh/packse/pull/227.

Could you suggest how I should test it?

This updates the surrounding code to use the new ResolverEnvironment
type. In some cases, this simplifies caller code by removing case
analysis. There *shouldn't* be any behavior changes here. Some test
snapshots were updated to account for some minor tweaks to error
messages.
I didn't split this up into separate commits because it would have been
too difficult/costly.
This type is intended to replace `ResolverMarkers`. The main difference
between them is that this type encapsulates more decision making by
un-exporting the different cases. So instead of callers needing to do
explicit case analysis depending on the type of resolver environment,
callers instead use methods that know how to do the right thing. In the
next commit, there are at least a few cases where this greatly
simplifies case analysis on the caller side.
The motivation for this type is to centralize decision making about
forking. In particular, we want to expand forking to include conflicting
groups instead of just `MarkerTree`. So to a certain extent, the
refactor here is about removing bare use of `MarkerTree` in favor of a
more purpose built type that encapsulates the forking logic.
The encapsulation is not quite perfect here. I expect to improve on it a
bit once we add support for conflicting groups.
This is split off from the subsequent commit (that makes use of
`ResolverEnvironment`) so that it's a bit easier to review the addition
in isolation.
## Summary
At present, when we have a Python requirement and we see a wheel, we
verify that the Python requirement is compatible with the wheel. For
source distributions, though, we verify that both the Python requirement
_and_ the currently-installed version are compatible, because we assume
that we'll need to build the source distribution in order to get
metadata. However, we can often extract source distribution metadata
_without_ building (e.g., if there's a `pyproject.toml` with no dynamic
keys).
This PR thus modifies the source distribution handling to defer that
incompatibility ("We couldn't get metadata for this project, because it
has no static metadata and requires a higher Python version to run /
build") until we actually try to build the package. As a result, you can
now resolve source distribution-only packages using Python versions
below their `requires-python`, as long as they include static metadata.
Closes https://github.com/astral-sh/uv/issues/8767.
## Summary
This PR improves the interaction of `--frozen` such that we reduce the
dependency on the `pyproject.toml` and increase the dependency on the
`uv.lock`. Specifically, we now read the list of workspace members from
the `uv.lock` rather than the `pyproject.toml`, which means we don't
need to discover the member `pyproject.toml` files in order to perform a
`uv sync --frozen --all-packages`.
## Summary
This PR enables `uv sync --all-packages` to sync all packages in a
workspace. It removes a common use-case for the legacy non-`[project]`
packages that we're trying to move away from.
Closes https://github.com/astral-sh/uv/issues/8724.
This PR fixes a bug where it was possible for dependencies to be
included in a final resolution with markers that always evaluate to
false. Specifically, `python_version < '0'`.
While we do filter based on Python markers during forking, it turns out
that the markers for each fork are "combined" *after* this filtering
step. But the process of combination can result in a more specific
marker that is always false for the configured Python requirement. This
could result in dependencies with markers that are always false (like
`python_version < '0'`) appearing in the resolution.
The first commit in this PR adds a regression test (with an undesirable
result), and the second commit fixes the regression and updates the
test.
Fixes#8676
## Summary
By default, `uv tree` shows the full workspace, not _just_ the root. If
the root depended on a workspace member as a dev dependency, then we'd
still show it as `(group: dev)` in `uv tree` even if you passed
`--no-dev`, because we weren't filtering the edges in the right place.
This is still somewhat confusing, because if `root` depends on workspace
member `child` as a dev dependency, `uv tree --no-dev` still shows both.
Closes https://github.com/astral-sh/uv/issues/8719.
Previously, when doing a `uv pip` resolution, we would only return the
first entry in the map. But there should only ever be one entry, or else
we would have incompatible dependencies. So we can collapse the case
with the "one universal fork" case.
(I found this while doing some refactoring of how we handle forking, and
collapsing these cases simplifies some of that refactoring work.)
When this code was written, we didn't have "proper" disjointness checks,
and so simple equality was used instead. Arguably disjointness checks
are
more correct, and this would also simplify some case analysis in an
ongoing
refactor.
## Summary
Unfortunately, it looks like we lost
https://github.com/astral-sh/uv/pull/8501 somewhere in a bad rebase.
This PR re-adds the change, with compatibility for those lockfiles
created in v0.4.27. I'm not certain we should actually merge this. It
might be less painful and confusing to just bite the bullet on the
change.

## Summary
It turns out we were omitting empty dependency groups from the lockfile
metadata, which was then causing us to reject locks when empty groups
were defined.
We now include them (that section of the lock is meant to be a true
representation of the metadata, and an empty-but-defined group is
different from an absent group), though we can ignore them for
validation, since it doesn't affect any behavior.
Closes https://github.com/astral-sh/uv/issues/8581.
## Summary
We already support `tool.uv.dev-dependencies` in the legacy
non-`[project]` projects. This adds equivalent support for
`[dependency-groups]`, e.g.:
```toml
[tool.uv.workspace]
[dependency-groups]
lint = ["ruff"]
```
This PR adds support for `tool.uv.default-groups`, which defaults to
`["dev"]` for backwards-compatibility. These represent the groups we
sync by default.
Part of #8090
Unblocks https://github.com/astral-sh/uv/pull/8274
Refactors `DevMode` and `DevSpecification` into a shared type
`DevGroupsSpecification` that allows us to track if `--dev` was
implicitly or explicitly provided.
Part of #8090
Adds the ability to add and remove dependencies from arbitrary groups
using `uv add` and `uv remove`. Does not include resolving with the new
dependencies — tackling that in #8110.
Additionally, this does not yet resolve interactions with the existing
`dev` group — we'll tackle that separately as well. I probably won't
merge the stack until that design is resolved.
## Summary
We were including dependencies that were only included by a dependency
that isn't relevant on the current platform (i.e., we were enforcing the
"current environment" at one level, but not transitively).
Closes https://github.com/astral-sh/uv/issues/8516.
## Summary
Historically, we haven't enforced schema versions. This PR adds a
versioning policy such that, if a uv version writes schema v2, then...
- It will always reject lockfiles with schema v3 or later.
- It _may_ reject lockfiles with schema v1, but can also choose to read
them, if possible.
(For example, the change we proposed to rename `dev-dependencies` to
`dependency-groups` would've been backwards-compatible: newer versions
of uv could still read lockfiles that used the `dev-dependencies` field
name, but older versions should reject lockfiles that use the
`dependency-groups` field name.)
Closes https://github.com/astral-sh/uv/issues/8465.
## Summary
Previously, `uv tree --package` had some strange behavior due to how we
were computing the root nodes. This PR refactors the entire
implementation to use `petgraph` so we can do proper operations on a
graph structure.
Closes https://github.com/astral-sh/uv/issues/8382.
## Summary
This is part of making
https://github.com/astral-sh/uv/issues/7299#issuecomment-2385286341
better. You can now use `tool.uv.dependency-metadata` for direct URL
requirements. Unfortunately, you _must_ include a version, since we need
one to perform resolution.
## Summary
If the user has an upper-bound in a `requires-python`, we don't
correctly narrow it during resolution. We should be narrowing based on
the intersection.
Closes#8297.
## Summary
Rather than relying on the distribution and package URL being the same
(which isn't true for Git dependencies), we can just use the
intersection of the markers directly.
Closes https://github.com/astral-sh/uv/issues/8381.
Part of https://github.com/astral-sh/uv/issues/2777
I noticed we're seeing "Python ABI" _a lot_ in error messages which I
did not expect. This improves a common case by being a little more
specific.
When patch version isn't specified and a matching version is referenced,
it will default patch to 0 which could be unclear/confusing. This PR
warns the user of that default.

## Summary
If you pass a named index via the CLI, you can now reference it as a
named source. This required some surprisingly large refactors, since we
now need to be able to track whether a given index was provided on the
CLI vs. elsewhere (since, e.g., we don't want users to be able to
reference named indexes defined in global configuration).
Closes https://github.com/astral-sh/uv/issues/7899.
## Summary
This PR lifts the restriction that a package must come from a single
index. For example, you can now do:
```toml
[project]
name = "project"
version = "0.1.0"
readme = "README.md"
requires-python = ">=3.12"
dependencies = ["jinja2"]
[tool.uv.sources]
jinja2 = [
{ index = "torch-cu118", marker = "sys_platform == 'darwin'"},
{ index = "torch-cu124", marker = "sys_platform != 'darwin'"},
]
[[tool.uv.index]]
name = "torch-cu118"
url = "https://download.pytorch.org/whl/cu118"
[[tool.uv.index]]
name = "torch-cu124"
url = "https://download.pytorch.org/whl/cu124"
```
The construction is very similar to the way we handle URLs today: you
can have multiple URLs for a given package, but they must appear in
disjoint forks. So most of the code is just adding that abstraction to
the resolver, following our handling of URLs.
Closes#7761.
## Summary
This PR enables users to provide index credentials via named environment
variables.
For example, given an index named `internal` that requires a username
(`public`) and password
(`koala`), you can define the index (without credentials) in your
`pyproject.toml`:
```toml
[[tool.uv.index]]
name = "internal"
url = "https://pypi-proxy.corp.dev/simple"
```
Then set the `UV_INDEX_INTERNAL_USERNAME` and
`UV_INDEX_INTERNAL_PASSWORD`
environment variables, where `INTERNAL` is the uppercase version of the
index name:
```sh
export UV_INDEX_INTERNAL_USERNAME=public
export UV_INDEX_INTERNAL_PASSWORD=koala
```
## Summary
This PR adds a first-class API for defining registry indexes, beyond our
existing `--index-url` and `--extra-index-url` setup.
Specifically, you now define indexes like so in a `uv.toml` or
`pyproject.toml` file:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
```
You can also provide indexes via `--index` and `UV_INDEX`, and override
the default index with `--default-index` and `UV_DEFAULT_INDEX`.
### Index priority
Indexes are prioritized in the order in which they're defined, such that
the first-defined index has highest priority.
Indexes are also inherited from parent configuration (e.g., the
user-level `uv.toml`), but are placed after any indexes in the current
project, matching our semantics for other array-based configuration
values.
You can mix `--index` and `--default-index` with the legacy
`--index-url` and `--extra-index-url` settings; the latter two are
merely treated as unnamed `[[tool.uv.index]]` entries.
### Index pinning
If an index includes a name (which is optional), it can then be
referenced via `tool.uv.sources`:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
[tool.uv.sources]
torch = { index = "pytorch" }
```
If an index is marked as `explicit = true`, it can _only_ be used via
such references, and will never be searched implicitly:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
explicit = true
[tool.uv.sources]
torch = { index = "pytorch" }
```
Indexes defined outside of the current project (e.g., in the user-level
`uv.toml`) can _not_ be explicitly selected.
(As of now, we only support using a single index for a given
`tool.uv.sources` definition.)
### Default index
By default, we include PyPI as the default index. This remains true even
if the user defines a `[[tool.uv.index]]` -- PyPI is still used as a
fallback. You can mark an index as `default = true` to (1) disable the
use of PyPI, and (2) bump it to the bottom of the prioritized list, such
that it's used only if a package does not exist on a prior index:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
default = true
```
### Name reuse
If a name is reused, the higher-priority index with that name is used,
while the lower-priority indexes are ignored entirely.
For example, given:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
[[tool.uv.index]]
name = "pytorch"
url = "https://test.pypi.org/simple"
```
The `https://test.pypi.org/simple` index would be ignored entirely,
since it's lower-priority than `https://download.pytorch.org/whl/cu121`
but shares the same name.
Closes#171.
## Future work
- Users should be able to provide authentication for named indexes via
environment variables.
- `uv add` should automatically write `--index` entries to the
`pyproject.toml` file.
- Users should be able to provide multiple indexes for a given package,
stratified by platform:
```toml
[tool.uv.sources]
torch = [
{ index = "cpu", markers = "sys_platform == 'darwin'" },
{ index = "gpu", markers = "sys_platform != 'darwin'" },
]
```
- Users should be able to specify a proxy URL for a given index, to
avoid writing user-specific URLs to a lockfile:
```toml
[[tool.uv.index]]
name = "test"
url = "https://private.org/simple"
proxy = "http://<omitted>/pypi/simple"
```
## Summary
This PR declares and documents all environment variables that are used
in one way or another in `uv`, either internally, or externally, or
transitively under a common struct.
I think over time as uv has grown there's been many environment
variables introduced. Its harder to know which ones exists, which ones
are missing, what they're used for, or where are they used across the
code. The docs only documents a handful of them, for others you'd have
to dive into the code and inspect across crates to know which crates
they're used on or where they're relevant.
This PR is a starting attempt to unify them, make it easier to discover
which ones we have, and maybe unlock future posibilities in automating
generating documentation for them.
I think we can split out into multiple structs later to better organize,
but given the high influx of PR's and possibly new environment variables
introduced/re-used, it would be hard to try to organize them all now
into their proper namespaced struct while this is all happening given
merge conflicts and/or keeping up to date.
I don't think this has any impact on performance as they all should
still be inlined, although it may affect local build times on changes to
the environment vars as more crates would likely need a rebuild. Lastly,
some of them are declared but not used in the code, for example those in
`build.rs`. I left them declared because I still think it's useful to at
least have a reference.
Did I miss any? Are their initial docs cohesive?
Note, `uv-static` is a terrible name for a new crate, thoughts? Others
considered `uv-vars`, `uv-consts`.
## Test Plan
Existing tests
As per
https://matklad.github.io/2021/02/27/delete-cargo-integration-tests.html
Before that, there were 91 separate integration tests binary.
(As discussed on Discord — I've done the `uv` crate, there's still a few
more commits coming before this is mergeable, and I want to see how it
performs in CI and locally).
## Summary
In the routine we use to verify whether the lockfile is up-to-date, we
sometimes have to resolve package metadata. If that resolution step
fails, the resolver is left in a bad state, as various tasks are marked
as pending despite the error. Treating that as a recoverable failure
thus leads to a deadlock.
This PR modifies the errors to be treated as fatal.
I think a more holistic fix here would be to add some kind of guard to
ensure that any tasks that fail are no longer marked as pending (or
enforce this in the type system).
Closes https://github.com/astral-sh/uv/issues/8074.
## Summary
The issue here is that, if you user has a `requires-python` like `>=
3.7, != 3.8.5`, this gets expanded to the following bounds:
- `[3.7, 3.8.5)`
- `(3.8.5, ...`
We then convert this to the specific `>= 3.7, < 3.8.5, > 3.8.5`. But the
commas in that expression are conjunctions... So it's impossible to
satisfy? No version is both `< 3.8.5` and `> 3.8.5`.
Instead, we now preserve the input `requires-python` and just
concatenate the terms, only using PubGrub to compute the _bounds_.
Closes https://github.com/astral-sh/uv/issues/7862.
Unlike `cp36-...`, which requires exactly CPython 3.6, `py36-none` is
compatible with all versions starting at Python 3.6.
Note that `py3x-none` should not be used. Instead, use `py3-none` with
`requires-python`.
Fixes#7800
## Summary
If a supported environment includes a Python marker, we don't simplify
it out, despite _storing_ the simplified markers. This PR modifies the
validation code to compare simplified to simplified markers.
Closes https://github.com/astral-sh/uv/issues/7876.
## Summary
When using `uv tree --package foo`, an extra empty line appears at the
beginning, which seems unnecessary since `uv tree` without the package
option doesn’t have this. It’s possible that the intention was to add
separation between packages, i.e. the correct implementation shoule be:
```rust
if !std::mem::take(&mut first) {
lines.push(String::new());
}
```
Even if corrected, this extra spacing might be redundant as `uv tree`
doesn’t include these empty lines between packages by default.
```console
$ uv init project
$ cd project
$ uv init foo
$ uv tree
Using CPython 3.12.5
Resolved 2 packages in 1ms
foo v0.1.0
project v0.1.0
$ uv tree --package project
Using CPython 3.12.5
Resolved 2 packages in 1ms
project v0.1.0
```
Would it be okay to expose this struct? We currently use our own
ResolveProvider, and it would be nice to use the `FlatDistributions` for
easy `VersionMap` creation.
Thanks!
## Summary
`click` has one dependency of `colorama` only on Windows, `uv tree
--invert` should not include `colorama` on non-Windows platforms, but
currently:
```console
$ uv init
$ uv add click
$ uv tree --invert --python-platform macos
colorama v0.4.6
```
it should:
```console
$ uv tree --invert --python-platform macos
click v8.1.7
└── project v0.1.0
```
#7226 modified the check to skip prefetching of source dists without
proper minimum-version bounds, and wound up flipping the boolean
expression. This change flips the some/none expression so that the
intended skip happens as expected.
Fixes#7680.
This PR adds some additional sanity checking on resolution graphs to
ensure we can never install different versions of the same package into
the same environment.
I used code similar to this to provoke bugs in the resolver before the
release, but it never made it into `main`. Here, we add the error
checking to the creation of `ResolutionGraph`, since this is where it's
most convenient to access the "full" markers of each distribution.
We only report an error when `debug_assertions` are enabled to avoid
rendering `uv` *completely* unusuable if a bug were to occur in a
production binary. For example, maybe a conflict is detected in a marker
environment that isn't actually used. While not ideal, `uv` is still
usable for any other marker environment.
Closes#5598
This enhances the hints generator in the resolver with some heuristic to
detect and warn in case of failures due to version mismatches on a local
package. Those may be the symptom of name conflict/shadowing with a
transitive dependency.

Recently, rkyv 0.8 was released. Its API is a fair bit simpler now for
higher level uses (like for us in `uv`) and results in us being able to
delete a fair bit of code. This also removes our last dependency on `syn
1.0`, and thus drops that dependency.
Performance (via testing on the `transformers` example) seems to remain
about the same, which is what was expected:
```
$ hyperfine -w5 -r100 'uv lock' 'uv-ag-rkyv-update lock'
Benchmark 1: uv lock
Time (mean ± σ): 55.6 ms ± 6.4 ms [User: 30.4 ms, System: 35.1 ms]
Range (min … max): 43.0 ms … 73.1 ms 100 runs
Benchmark 2: uv-ag-rkyv-update lock
Time (mean ± σ): 56.5 ms ± 7.2 ms [User: 30.5 ms, System: 36.3 ms]
Range (min … max): 39.1 ms … 71.5 ms 100 runs
Summary
uv lock ran
1.02 ± 0.18 times faster than uv-ag-rkyv-update lock
```
Closes#7415
This changes the structure of the hints generator in the resolver when
encountering solution errors, so that it re-uses a single output buffer
owned by the caller.
It avoids repeated allocations of a temporary buffer within each
recursive function call.
## Summary
This PR enables users to provide pre-defined static metadata for
dependencies. It's intended for situations in which the user depends on
a package that does _not_ declare static metadata (e.g., a
`setup.py`-only sdist), and that is expensive to build or even cannot be
built on some architectures. For example, you might have a Linux-only
dependency that can't be built on ARM -- but we need to build that
package in order to generate the lockfile. By providing static metadata,
the user can instruct uv to avoid building that package at all.
For example, to override all `anyio` versions:
```toml
[project]
name = "project"
version = "0.1.0"
requires-python = ">=3.12"
dependencies = ["anyio"]
[[tool.uv.dependency-metadata]]
name = "anyio"
requires-dist = ["iniconfig"]
```
Or, to override a specific version:
```toml
[project]
name = "project"
version = "0.1.0"
requires-python = ">=3.12"
dependencies = ["anyio"]
[[tool.uv.dependency-metadata]]
name = "anyio"
version = "3.7.0"
requires-dist = ["iniconfig"]
```
The current implementation uses `Metadata23` directly, so we adhere to
the exact schema expected internally and defined by the standards. Any
entries are treated similarly to overrides, in that we won't even look
for `anyio@3.7.0` metadata in the above example. (In a way, this also
enables #4422, since you could remove a dependency for a specific
package, though it's probably too unwieldy to use in practice, since
you'd need to redefine the _rest_ of the metadata, and do that for every
package that requires the package you want to omit.)
This is under-documented, since I want to get feedback on the core ideas
and names involved.

## Summary
All the registry wheels were getting cached under
`index/b2a7eb67d4c26b82` rather than `pypi`, because we used
`IndexUrl::Url` rather than `IndexUrl::from`.
