This commit makes intra-doc link tooltips consistent with generated
links in function signatures and item tables, with the format
`itemtype foo::bar::baz`. This way, you can tell if a link points at
a trait or a type (for example) by mousing over it.

Added another error to be processed in fallback
This pull request addresses the problem of Rust not being able to read file/directory metadata because the current user doesn't have permission to read the file and are thus inaccessible.
One particular example is `System Volume Information`. But any example can be made by having a file/directory, which the current user can't access even though the system does allow to view the metadata, which is handled by the fallback.
The fallback exists to get the metadata but it was limited to one error type. Having added ERROR_ACCESS_DENIED per Chris Denton's suggestion, file/directory properties are now properly read.
Solution suggested by Chris Denton https://github.com/nushell/nushell/issues/6857#issuecomment-1426847135
Clearly document intentional UB in mir-opt tests
All of the changed mir-opt test input files did not pass Miri. Now they do.
r? `@cjgillot` because there's a CopyProp test in here that I do not fully understand
Allow shortcuts to directories to be used for ./x.py fmt
Fixes#107944.
Maximum recursive search depth is 3 and only accepts shortcuts for directories. If there are no shortcut candidates, the previous behavior to panic is preserved. If there are multiple candidates, the shortcut candidates are ignored.
After this change, `./x.py fmt std` no longer panics and formats `library/std` instead.
Update broken link in cargo style guide
Toml now uses [toml.io](https://toml.io) for released specifications and the github repo for development. Also the old link was for the 0.4 specification, while cargo uses toml_edit, which uses toml 1.0 (reference:
https://github.com/toml-rs/toml/blob/main/crates/toml_edit/CHANGELOG.md#030---2021-09-13). Finally the discussion of "Bare keys" vs "Quoted keys" has moved from the `#table` section to `#keys`.
fix: improve the suggestion on future not awaited
Considering the following code
```rust
fn foo() -> u8 {
async fn async_fn() -> u8 { 22 }
async_fn()
}
fn main() {}
```
the error generated before this commit from the compiler is
```
➜ rust git:(macros/async_fn_suggestion) ✗ rustc test.rs --edition 2021
error[E0308]: mismatched types
--> test.rs:4:5
|
1 | fn foo() -> u8 {
| -- expected `u8` because of return type
...
4 | async_fn()
| ^^^^^^^^^^ expected `u8`, found opaque type
|
= note: expected type `u8`
found opaque type `impl Future<Output = u8>`
help: consider `await`ing on the `Future`
|
4 | async_fn().await
| ++++++
error: aborting due to previous error
```
In this case the error is nor perfect, and can confuse the user that do not know that the opaque type is the future.
So this commit will propose (and conclude the work start in https://github.com/rust-lang/rust/issues/80658)
to change the string `opaque type` to `future` when applicable and also remove the Expected vs Received note by adding a more specific one regarding the async function that return a future type.
So the new error emitted by the compiler is
```

Fixes https://github.com/rust-lang/rust/issues/80658
It remains to rework the case described in the following issue https://github.com/rust-lang/rust/issues/107899 but I think this deserves its own PR after we discuss a little bit how to handle these kinds of cases.

Fixes#107944.
Maximum recursive search depth is 3 and only accepts shortcuts for
directories (single component paths, such as `./x.py fmt std`). If
there are no shortcut candidates but single componenet path(s) are
given, it falls back to the previous behavior to panic with unable to
find directory. If there are multiple shortcut candidates for a given
single component path, the shortcut candidates are considered
ambiguous, are then ignored, and the single component path is accepted
as-is.
After this change, `./x.py fmt std` no longer panics and formats
`library/std` instead.
Move folding & visiting traits into type library
This is a rework of #107712, following feedback on that PR.
In particular, this version uses trait aliases to reduce the API churn for trait consumers. Doing so requires a workaround for #107747 until its fix in #107803 is merged into the stage0 compiler; this workaround, which uses conditional compilation based on the `bootstrap` configuration predicate, sits in dedicated commit b409329c for ease of reversion.
The possibility of the `rustc_middle` crate retaining its own distinct versions of each folding/visiting trait, blanket-implemented on all types that implement the respective trait in the type library, was also explored: however since this would necessitate making each `rustc_middle` trait a subtrait of the respective type library trait (so that such blanket implementations can delegate their generic methods), no benefit would be gained.
