Update rustc book CLI docs.
This adds a little detail (and missing flags) to the rustc book. There is still a lot of information missing, but this seemed like a good step to expanding it.
Include expression to wait for to the span of Await
Currently the span of `await!` only includes itself:
```rust
await!(3);
// ^^^^^
```
This PR changes it so that the span holds the whole `await!` expression:
```rust
await!(3);
// ^^^^^^^^^
string: implement From<&String> for String
Allow Strings to be created from borrowed Strings. This is mostly
to make things like passing `&String` to an `impl Into<String>`
parameter frictionless.
Fixes#59827.
Move token tree related lexer state to a separate struct
Just a types-based refactoring.
We only used a bunch of fields when tokenizing into a token tree, so let's move them out of the base lexer
- add comment explaining that the fast::Key data structure was carefully constructed for fast access on OSX
- remove inline(never) from the initializer for types where `needs_drop::<T>()` is false
Remove bitrig support from rust
Resolves#60743
using `find` and `rg` I delete every occurence of "bitrig" in the sources, expect for the llvm submodule (is this correct?).
There's also this file 5b8e99bb61/rls-analysis/test_data/rust-analysis/libstd-af9bacceee784405.json which contains a bitrig string in it. What to do with that?
