 Finally, regenerate the documentation and generated code with `cargo dev generate-all`.
 ### Opening a PR
 After you finish your changes, the next step is to open a PR. By default, two
 sections will be filled into the PR body: the summary and the test plan.
 #### The summary
 The summary is intended to give us as maintainers information about your PR.
 This should typically include a link to the relevant issue(s) you're addressing
 in your PR, as well as a summary of the issue and your approach to fixing it. If
 you have any questions about your approach or design, or if you considered
 alternative approaches, that can also be helpful to include.
 AI can be helpful in generating both the code and summary of your PR, but a
 successful contribution should still be carefully reviewed by you and the
 summary editorialized before submitting a PR. A great summary is thorough but
 also succinct and gives us the context we need to review your PR.
 You can find examples of excellent issues and PRs by searching for the
 [`great writeup`](https://github.com/astral-sh/ruff/issues?q=label%3A%22great%20writeup%22)
 label.
 #### The test plan
 The test plan is likely to be shorter than the summary and can be as simple as
 "Added new snapshot tests for `RUF123`," at least for rule bugs. For LSP or some
 types of CLI changes, in particular, it can also be helpful to include
 screenshots or recordings of your change in action.
 #### Ecosystem report
 After opening the PR, an ecosystem report will be run as part of CI. This shows
 a diff of linter and formatter behavior before and after the changes in your PR.
 Going through these changes and reporting your findings in the PR summary or an
 additional comment help us to review your PR more efficiently. It's also a great
 way to find new test cases to incorporate into your PR if you identify any
 issues.
 #### PR status
 To help us know when your PR is ready for review again, please either move your
 PR back to a draft while working on it (marking it ready for review afterwards
 will ping the previous reviewers) or explicitly re-request a review. This helps
 us to avoid re-reviewing a PR while you're still working on it and also to
 prioritize PRs that are definitely ready for review.
 You can also thumbs-up or mark as resolved any comments we leave to let us know
 you addressed them.

This can result in both different and\nmore import statements being marked as unused.\n\nFor example, if a module consists of\n\n```python\nimport a\nimport a.b\n```\n\nthen both statements are marked as unused under [preview], whereas\nonly the second is marked as unused under stable behavior.\n\nAs another example, if a module consists of\n\n```python\nimport a.b\nimport a\n\na.b.foo()\n```\n\nthen a diagnostic will only be emitted for the first line under [preview],\nwhereas a diagnostic would only be emitted for the second line under\nstable behavior.\n\nNote that this behavior is somewhat subjective and is designed\nto conform to the developer's intuition rather than Python's actual\nexecution. To wit, the statement `import a.b` automatically executes\n`import a`, so in some sense `import a` is _always_ redundant\nin the presence of `import a.b`.\n\n\n## Fix safety\n\nFixes to remove unused imports are safe, except in `__init__.py` files.\n\nApplying fixes to `__init__.py` files is currently in preview. The fix offered depends on the\ntype of the unused import. Ruff will suggest a safe fix to export first-party imports with\neither a redundant alias or, if already present in the file, an `__all__` entry. If multiple\n`__all__` declarations are present, Ruff will not offer a fix. Ruff will suggest an unsafe fix\nto remove third-party and standard library imports -- the fix is unsafe because the module's\ninterface changes.\n\nSee [this FAQ section](https://docs.astral.sh/ruff/faq/#how-does-ruff-determine-which-of-my-imports-are-first-party-third-party-etc)\nfor more details on how Ruff\ndetermines whether an import is first or third-party.\n\n## Example\n\n```python\nimport numpy as np  # unused import\n\n\ndef area(radius):\n    return 3.14 * radius**2\n```\n\nUse instead:\n\n```python\ndef area(radius):\n    return 3.14 * radius**2\n```\n\nTo check the availability of a module, use `importlib.util.find_spec`:\n\n```python\nfrom importlib.util import find_spec\n\nif find_spec(\"numpy\") is not None:\n    print(\"numpy is installed\")\nelse:\n    print(\"numpy is not installed\")\n```\n\n## Options\n- `lint.ignore-init-module-imports`\n- `lint.pyflakes.allowed-unused-imports`\n\n## References\n- [Python documentation: `import`](https://docs.python.org/3/reference/simple_stmts.html#the-import-statement)\n- [Python documentation: `importlib.util.find_spec`](https://docs.python.org/3/library/importlib.html#importlib.util.find_spec)\n- [Typing documentation: interface conventions](https://typing.python.org/en/latest/spec/distributing.html#library-interface-public-and-private-symbols)\n\n[preview]: https://docs.astral.sh/ruff/preview/\n",

 # unused-import (F401)
 Derived from the **Pyflakes** linter.
 Fix is sometimes available.
 ## What it does
 Checks for unused imports.
 ## Why is this bad?
 Unused imports add a performance overhead at runtime, and risk creating
 import cycles. They also increase the cognitive load of reading the code.
 If an import statement is used to check for the availability or existence
 of a module, consider using `importlib.util.find_spec` instead.
 If an import statement is used to re-export a symbol as part of a module's
 public interface, consider using a "redundant" import alias, which
 instructs Ruff (and other tools) to respect the re-export, and avoid
 marking it as unused, as in:
 ```python
 from module import member as member
 ```
 Alternatively, you can use `__all__` to declare a symbol as part of the module's
 interface, as in:
 ```python
 # __init__.py
 import some_module
 __all__ = ["some_module"]
 ```
 ## Preview
 When [preview] is enabled (and certain simplifying assumptions
 are met), we analyze all import statements for a given module
 when determining whether an import is used, rather than simply
 the last of these statements. This can result in both different and
 more import statements being marked as unused.
 For example, if a module consists of
 ```python
 import a
 import a.b
 ```
 then both statements are marked as unused under [preview], whereas
 only the second is marked as unused under stable behavior.
 As another example, if a module consists of
 ```python
 import a.b
 import a
 a.b.foo()
 ```
 then a diagnostic will only be emitted for the first line under [preview],
 whereas a diagnostic would only be emitted for the second line under
 stable behavior.
 Note that this behavior is somewhat subjective and is designed
 to conform to the developer's intuition rather than Python's actual
 execution. To wit, the statement `import a.b` automatically executes
 `import a`, so in some sense `import a` is _always_ redundant
 in the presence of `import a.b`.
 ## Fix safety
 Fixes to remove unused imports are safe, except in `__init__.py` files.
 Applying fixes to `__init__.py` files is currently in preview. The fix offered depends on the
 type of the unused import. Ruff will suggest a safe fix to export first-party imports with
 either a redundant alias or, if already present in the file, an `__all__` entry. If multiple
 `__all__` declarations are present, Ruff will not offer a fix. Ruff will suggest an unsafe fix
 to remove third-party and standard library imports -- the fix is unsafe because the module's
 interface changes.
 See [this FAQ section](https://docs.astral.sh/ruff/faq/#how-does-ruff-determine-which-of-my-imports-are-first-party-third-party-etc)
 for more details on how Ruff
 determines whether an import is first or third-party.
 ## Example
 ```python
 import numpy as np  # unused import
 def area(radius):
    return 3.14 * radius**2
 ```
 Use instead:
 ```python
 def area(radius):
    return 3.14 * radius**2
 ```
 To check the availability of a module, use `importlib.util.find_spec`:
 ```python
 from importlib.util import find_spec
 if find_spec("numpy") is not None:
    print("numpy is installed")
 else:
    print("numpy is not installed")
 ```
