Also fix the `needs_drop()` intrinsic.
Unions also need this information (to err if they have a drop-needing field), but this will come in a follow-up PR.
There were two mistakes: first, tests were sorted before test modules, and second, we re-sorted based on the name only, which cancelled the sort based on the kind.
And add a new diagnostic for non-`Fn` parenthesized generic args.
Path lowering started to look like a mess, with each function carrying additional parameters for the diagnostic callback (since paths can occur both in type and in expression/pattern position, and their diagnostic handling is different) and the segment index, for the diagnostics report. So I refactored it from stateless functions on `TyLoweringContext` into stateful struct, `PathLoweringContext`, that tracks the process of lowering a path from resolution til assoc types selection.
The reason this test passed previously is not because it was working as intended, but because prior to the previous commit we did not resolve the `use` at all!
Now, `use self as _` is invalid code anyway (it prints E0429), and because we fallback to the value namespace if we can't resolve in the type namespace (which is a reasonable behavior), this test now actually fails.
I don't think we want to change the fallback, so I removed `use self as _` and instead added a new test, where the value can be resolved in the type namespace.
It should be considered by the edition of the caller, not the callee.
Technically we still don't do it correctly - we need the span of the method name (if it comes from a macro), but we don't keep it and this is good enough for now.
Split manual.adoc into markdown files, one for each chapter.
For the parts of the manual that are generated from source code doc
comments, update the comments to use markdown syntax and update the
code generators to write to `generated.md` files.
For the weekly release, stop copying the .adoc files to the
`rust-analyzer/rust-analyzer.github.io` at release time. Instead,
we'll sync the manual hourly from this repository.
See https://github.com/rust-analyzer/rust-analyzer.github.io/pull/226
for the sync. This PR should be merged first, and that PR needs to be
merged before the next weekly release.
This change is based on #15795, but rebased and updated. I've also
manually checked each page for markdown syntax issues and fixed any I
encountered.
