Bump its stabilization version several times along the way to accommodate changes in release processes. Co-authored-by: Mara Bos <m-ou.se@m-ou.se> Co-authored-by: Trevor Gross <t.gross35@gmail.com>
Stabilize const-weak-new
This is a fairly uncontroversial library stabilization, so I'm going ahead and proposing it to ride the trains to stable.
This stabilizes the following APIs, which are defined to be non-allocating constructors.
```rust
// alloc::rc
impl<T> Weak<T> {
pub const fn new() -> Weak<T>;
}
// alloc::sync
impl<T> Weak<T> {
pub const fn new() -> Weak<T>;
}
```
Closes rust-lang#95091

…ngjubilee Use `LazyLock` to lazily resolve backtraces By using TAIT to name the initializing closure, `LazyLock` can be used to replace the current `LazilyResolvedCapture`.
…-missing-opaque, r=spastorino Don't install default projection bound for return-position `impl Trait` in trait methods with no body This ensures that we never try to project to an opaque type in a trait method that has no body to infer its hidden type, which means we never later call `type_of` on that opaque. This is because opaque types try to reveal their hidden type when proving auto traits. I thought about this a lot, and I think this is a fix that's less likely to introduce other strange downstream ICEs than rust-lang#113461. r? `@spastorino`
…er-errors Fix simd_bswap for i8/u8 rust-lang#114156 missed this test case☹️ cc `@workingjubilee`
Fix empty_write since rust version attribute Fixup of rust-lang#98154 for the rust version. r? `@workingjubilee`
