## Summary When you try to remove an internal representation leaking into another type and end up rewriting a simple version of `smallvec`. The goal of this PR is to replace the `Box<[&'a str]>` with `Box<QualifiedName>` to avoid that the internal `QualifiedName` representation leaks (and it gives us a nicer API too). However, doing this when `QualifiedName` uses `SmallVec` internally gives us all sort of funny lifetime errors. I was lost but @BurntSushi came to rescue me. He figured out that `smallvec` has a variance problem which is already tracked in https://github.com/servo/rust-smallvec/issues/146 To fix the variants problem, I could use the smallvec-2-alpha-4 or implement our own smallvec. I went with implementing our own small vec for this specific problem. It obviously isn't as sophisticated as smallvec (only uses safe code), e.g. it doesn't perform any size optimizations, but it does its job. Other changes: * Removed `Imported::qualified_name` (the version that returns a `String`). This can be replaced by calling `ToString` on the qualified name. * Renamed `Imported::call_path` to `qualified_name` and changed its return type to `&QualifiedName`. * Renamed `QualifiedName::imported` to `user_defined` which is the more common term when talking about builtins vs the rest/user defined functions. ## Test plan `cargo test` |
