The main workspace, bootstrap, cargo, miri, and rust-analyzer all lock
serde to different versions. It's preferable to share the same version
where possible, so update it.
Rustfmt is synced from another repository and has its own Cargo.lock,
but since it's added to the overall workspace it should respect the
version here.
Cargo is already at the latest version. Miri and rust-analyzer would
require upstream updates.
Constify `[u8]::is_ascii` (unstably)
UTF-8 checking in `const fn`-stabilized back in 1.63 (#97367), but apparently somehow ASCII checking was never const-ified, despite being simpler.
New constness-tracking issue for `is_ascii`: #111090
I noticed this working on `ascii::Char`: #110998
Support return-type bounds on associated methods from supertraits
Support `T: Trait<method(): Bound>` when `method` comes from a supertrait, aligning it with the behavior of associated type bounds (both equality and trait bounds).
The only wrinkle is that I have to extend `super_predicates_that_define_assoc_type` to look for *all* items, not just `AssocKind::Ty`. This will also be needed to support `feature(associated_const_equality)` as well, which is subtly broken when it comes to supertraits, though this PR does not fix those yet. There's a slight chance there's a perf regression here, in which case I guess I could split it out into a separate query.
This function/lang_item was introduced in #104321 as a temporary workaround of future lowering.
The usage and need for it went away in #104833.
After a bootstrap update, the function itself can be removed from `std`.

Remove calls to `mem::forget` and `mem::replace` in `Option::get_or_insert_with`.
This removes the unneeded calls to `mem::forget` and `mem::replace` in `Option::get_or_insert_with`.
Emit while_true lint spanning the entire loop condition
The lint that suggests `loop {}` instead of `while true {}` has functionality to 'pierce' parenthesis in cases like `while (true) {}`. In these cases, the emitted span only went to the hi of the `true` itself, not spanning the entire loop condition.
Before:
```
warning: denote infinite loops with `loop { ... }`
--> /tmp/foobar.rs:2:5
|
2 | while ((((((true)))))) {}
| ^^^^^^^^^^^^^^^^ help: use `loop`
|
= note: `#[warn(while_true)]` on by default
```
After:
```
warning: denote infinite loops with `loop { ... }`
--> /tmp/foobar.rs:2:5
|
2 | while ((((((true)))))) {}
| ^^^^^^^^^^^^^^^^^^^^^^ help: use `loop`
|
= note: `#[warn(while_true)]` on by default
```
This is especially a problem for rustfix.
added TraitAlias to check_item() for missing_docs
As in issue #111025 the `missing_docs` was not being triggered for trait aliases. I added `TraitAlias` to the pattern match for check_item(), and the lint seems to be behaving appropriately
clean up `transmute`s in `core`
* Use `transmute_unchecked` instead of `transmute_copy` for `MaybeUninit::transpose`.
* Use manual transmute for `Option<Ordering>` → `i8`.
Operand::extract_field: only cast llval if it's a pointer and replace bitcast w/ pointercast.
Fixes#105439.
Also cc `@erikdesjardins,` looks like another place to cleanup as part of #105545
Migrate bootstrap to Clap-based argument parsing
Supercedes #108083
I chose to re-do the work rather than rebase the onto the large changes since the original PR. If it's preferred I can instead force-push the original PR to this version.
