  <summary>Recommended update for rust</summary>
  <description>This update for rust fixes the following issues:

Version 1.82.0 (2024-10-17)
==========================

Language
--------

- Don't make statement nonterminals match pattern nonterminals
- Patterns matching empty types can now be omitted in common cases
- Enforce supertrait outlives obligations when using trait impls
- `addr_of(_mut)!` macros and the newly stabilized `&amp;raw (const|mut)` are now safe to use with all static items
- size_of_val_raw: for length 0 this is safe to call
- Reorder trait bound modifiers *after* `for&lt;...&gt;` binder in trait bounds
- Stabilize opaque type precise capturing (RFC 3617)
- Stabilize `&amp;raw const` and `&amp;raw mut` operators (RFC 2582)
- Stabilize unsafe extern blocks (RFC 3484)
- Stabilize nested field access in `offset_of!`
- Do not require `T` to be live when dropping `[T; 0]`
- Stabilize `const` operands in inline assembly
- Stabilize floating-point arithmetic in `const fn`
- Stabilize explicit opt-in to unsafe attributes
- Document NaN bit patterns guarantees

Compiler
--------

- Promote riscv64gc-unknown-linux-musl to tier 2
- Promote Mac Catalyst targets `aarch64-apple-ios-macabi` and `x86_64-apple-ios-macabi` to Tier 2, and ship them with rustup
- Add tier 3 NuttX based targets for RISC-V and ARM
- Add tier 3 powerpc-unknown-linux-muslspe target
- Improved diagnostics to explain why a pattern is unreachable
- The compiler now triggers the unreachable code warning properly for async functions that don't return/are `-&gt; !`
- Promote `aarch64-apple-darwin` to Tier 1
- Add Trusty OS target `aarch64-unknown-trusty` and `armv7-unknown-trusty` as tier 3 targets
- Promote `wasm32-wasip2` to Tier 2.

Libraries
---------

- Generalize `{Rc,Arc}::make_mut()` to `Path`, `OsStr`, and `CStr`.

Cargo

- feat: Add `info` cargo subcommand

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

- We now [disallow setting some built-in cfgs via the command-line with the newly added `explicit_builtin_cfgs_in_flags` https://doc.rust-lang.org/rustc/lints/listing/deny-by-default.html#explicit-builtin-cfgs-in-flags lint in order to prevent incoherent state, eg. `windows` cfg active but target is Linux based. The appropriate `rustc` flag https://doc.rust-lang.org/rustc/command-line-arguments.html should be used instead.
- The standard library has a new implementation of `binary_search` which is significantly improves performance. However when a sorted slice has multiple values which compare equal, the new implementation may select a different value among the equal ones than the old implementation.
- Removes a problematic hack that always passed the --whole-archive linker flag for tests, which may cause linker errors for code accidentally relying on it.
- The WebAssembly target features `multivalue` and `reference-types` are now
  both enabled by default. These two features both have subtle changes implied
  for generated WebAssembly binaries. For the `multivalue` feature, WebAssembly
  target support has changed when upgrading to LLVM 19. Support for generating
  functions with multiple returns no longer works and
  `-Ctarget-feature=+multivalue` has a different meaning than it did in LLVM 18
  and prior. There is no longer any supported means to generate a module that has
  a function with multiple returns in WebAssembly from Rust source code. For the
  `reference-types` feature the encoding of immediates in the `call_indirect`, a
  commonly used instruction by the WebAssembly backend, has changed. Validators
  and parsers which don't understand the `reference-types` proposal will no
  longer accept modules produced by LLVM due to this change in encoding of
  immediates. Additionally these features being enabled are encoded in the
  `target_features` custom section and may affect downstream tooling such as
  `wasm-opt` consuming the module. Generating a WebAssembly module that disables
  default features requires `-Zbuild-std` support from Cargo and more information
  can be found at [rust-lang/rust#128511]
- Rust now raises unsafety errors for union patterns in parameter-position
