## Description:

This update for rust, rust1.75 fixes the following issues:

This update ships rust 1.75.

# Version 1.75.0 (2023-12-28)

## Language

  * Stabilize `async fn` and return-position `impl Trait` in traits.
  * Allow function pointer signatures containing `&mut T` in `const`
    contexts.
  * Match `usize`/`isize` exhaustively with half-open ranges.
  * Guarantee that `char` has the same size and alignment as `u32`.
  * Document that the null pointer has the 0 address.
  * Allow partially moved values in `match`.
  * Add notes about non-compliant FP behavior on 32bit x86 targets.
  * Stabilize ratified RISC-V target features.

## Compiler

  * Rework negative coherence to properly consider impls that only partly
    overlap.
  * Bump `COINDUCTIVE_OVERLAP_IN_COHERENCE` to deny, and warn in dependencies.
  * Consider alias bounds when computing liveness in NLL.
  * Add the V (vector) extension to the `riscv64-linux-android` target spec.
  * Automatically enable cross-crate inlining for small functions

## Libraries

  * Override `Waker::clone_from` to avoid cloning `Waker`s unnecessarily.
  * Implement `BufRead` for `VecDeque<u8>`.
  * Implement `FusedIterator` for `DecodeUtf16` when the inner iterator does.
  * Implement `Not, Bit{And,Or}{,Assign}` for IP addresses.
  * Implement `Default` for `ExitCode`.
  * Guarantee representation of None in NPO
  * Document when atomic loads are guaranteed read-only.
  * Broaden the consequences of recursive TLS initialization.
  * Windows: Support sub-millisecond sleep.
  * Fix generic bound of `str::SplitInclusive`'s `DoubleEndedIterator` impl
  * Fix exit status / wait status on non-Unix `cfg(unix)` platforms.

## Stabilized APIs

  * `Atomic*::from_ptr`
  * `FileTimes`
  * `FileTimesExt`
  * `File::set_modified`
  * `File::set_times`
  * `IpAddr::to_canonical`
  * `Ipv6Addr::to_canonical`
  * `Option::as_slice`
  * `Option::as_mut_slice`
  * `pointer::byte_add`
  * `pointer::byte_offset`
  * `pointer::byte_offset_from`
  * `pointer::byte_sub`
  * `pointer::wrapping_byte_add`
  * `pointer::wrapping_byte_offset`
  * `pointer::wrapping_byte_sub`

These APIs are now stable in const contexts:

  * `Ipv6Addr::to_ipv4_mapped`
  * `MaybeUninit::assume_init_read`
  * `MaybeUninit::zeroed`
  * `mem::discriminant`
  * `mem::zeroed`

## Cargo

  * Add new packages to `[workspace.members
  * Allow version-less `Cargo.toml` manifests.
  * Make browser links out of HTML file paths.

## Rustdoc

  * Accept less invalid Rust in rustdoc.
  * Document lack of object safety on affected traits.
  * Hide `#[repr(transparent)
  * Show enum discriminant if it is a C-like variant.

## Compatibility Notes

  * Make misalignment a hard error in `const` contexts.
  * Fix detecting references to packed unsized fields.
  * Remove support for compiler plugins.
