   feature can now be installed.

Description:

   This update for rust, rust1.67 fixes the following issues:

   Rust is shipped in version 1.67.0.

   Changes in rust1.67:

   Version 1.67.0 (2023-01-26) ==========================

   Language
   --------

   - Make `Sized` predicates coinductive, allowing cycles.
   - #[must_use]` annotations on `async fn` also affect the `Future::Output`.
   - Elaborate supertrait obligations when deducing closure signatures.
   - Invalid literals are no longer an error under `cfg(FALSE)`.
   - Unreserve braced enum variants in value namespace.

   Compiler
   --------

   - Enable varargs support for calling conventions other than `C` or `cdecl`.
   - Add new MIR constant propagation based on dataflow analysis.
   - Optimize field ordering by grouping m\*2^n-sized fields with
     equivalently aligned ones.
   - Stabilize native library modifier `verbatim`.

   Added and removed targets:

   - Remove tier 3 `linuxkernel` targets Refer to Rust's platform support
     page for more information on Rust's tiered platform support.

   Libraries
   ---------

   - Merge `crossbeam-channel` into `std::sync::mpsc`.
   - Fix inconsistent rounding of 0.5 when formatted to 0 decimal places.
   - Derive `Eq` and `Hash` for `ControlFlow`.
   - Don't build `compiler_builtins` with `-C panic=abort`.

   Stabilized APIs
   ---------------

   - {integer}::checked_ilog
   - {integer}::checked_ilog2
   - {integer}::checked_ilog10
   - {integer}::ilog
   - {integer}::ilog2
   - {integer}::ilog10
   - NonZeroU*::ilog2
   - NonZeroU*::ilog10
   - NonZero*::BITS

   These APIs are now stable in const contexts:

   - char::from_u32
   - char::from_digit
   - char::to_digit
   - core::char::from_u32
   - core::char::from_digit

   Compatibility Notes
   -------------------

   - The layout of `repr(Rust)` types now groups m\*2^n-sized fields with
     equivalently aligned ones. This is intended to be an optimization, but
     it is also known to increase type sizes in a few cases for the placement
     of enum tags. As a reminder, the layout
     of `repr(Rust)` types is an implementation detail, subject to change.
   - 0.5 now rounds to 0 when formatted to 0 decimal places. This makes it
     consistent with the rest of floating point formatting that rounds ties
     toward even digits.
   - Chains of `&&` and `||` will now drop temporaries from their
     sub-expressions in evaluation order, left-to-right. Previously, it was
     "twisted" such that the _first_ expression dropped its temporaries
     _last_, after all of the other expressions dropped in order.
   - Underscore suffixes on string literals are now a hard error. This has
     been a future-compatibility warning since 1.20.0.
   - Stop passing `-export-dynamic` to `wasm-ld`.
   - main` is now mangled as `__main_void` on `wasm32-wasi`.
   - Cargo now emits an error if there are multiple registries in the
     configuration with the same index URL.
