An update that contains one feature can now be installed.

## Description:

This update for rust fixes the following issues:

  * Update to version 1.76.0 - for details see the rust1.76 package

# Version 1.76.0 (2024-02-08)

## Language

  * Document Rust ABI compatibility between various types
  * Also: guarantee that char and u32 are ABI-compatible
  * Warn against ambiguous wide pointer comparisons
  * Add lint `ambiguous_wide_pointer_comparisons` that supersedes
    `clippy::vtable_address_comparisons`

## Compiler

  * Lint pinned `#[must_use]` pointers (in particular, `Box<T>` where `T`
    is `#[must_use]`) in `unused_must_use`.
  * Soundness fix: fix computing the offset of an unsized field in a packed
    struct
  * Soundness fix: fix dynamic size/align computation logic for packed types
    with dyn Trait tail
  * Add `$message_type` field to distinguish json diagnostic outputs
  * Enable Rust to use the EHCont security feature of Windows
  * Add tier 3 {x86_64,i686}-win7-windows-msvc targets
  * Add tier 3 aarch64-apple-watchos target
  * Add tier 3 arm64e-apple-ios & arm64e-apple-darwin targets

Refer to Rust's [platform support page for more information on Rust's tiered
platform support.

## Libraries

  * Add a column number to `dbg!()`
  * Add `std::hash::{DefaultHasher, RandomState}` exports
  * Fix rounding issue with exponents in fmt
  * Add T: ?Sized to `RwLockReadGuard` and `RwLockWriteGuard`'s Debug impls.
  * Windows: Allow `File::create` to work on hidden files

## Stabilized APIs

  * `Arc::unwrap_or_clone` (https://doc.rust-
    lang.org/stable/std/sync/struct.Arc.html#method.unwrap_or_clone)
  * `Rc::unwrap_or_clone` (https://doc.rust-
    lang.org/stable/std/rc/struct.Rc.html#method.unwrap_or_clone)
  * `Result::inspect` (https://doc.rust-
    lang.org/stable/std/result/enum.Result.html#method.inspect)
  * `Result::inspect_err` (https://doc.rust-
    lang.org/stable/std/result/enum.Result.html#method.inspect_err)
  * `Option::inspect` (https://doc.rust-
    lang.org/stable/std/option/enum.Option.html#method.inspect)
  * `type_name_of_val` (https://doc.rust-
    lang.org/stable/std/any/fn.type_name_of_val.html)
  * `std::hash::{DefaultHasher, RandomState}` (https://doc.rust-
    lang.org/stable/std/hash/index.html#structs) These were previously available
    only through `std::collections::hash_map`.
  * `ptr::{from_ref, from_mut}` (https://doc.rust-
    lang.org/stable/std/ptr/fn.from_ref.html)
  * `ptr::addr_eq` (https://doc.rust-lang.org/stable/std/ptr/fn.addr_eq.html)

## Cargo

See Cargo release notes at https://github.com/rust-
lang/cargo/blob/master/CHANGELOG.md#cargo-176-2024-02-08 .

## Rustdoc

  * Don't merge cfg and doc(cfg) attributes for re-exports
  * rustdoc: allow resizing the sidebar / hiding the top bar
  * rustdoc-search: add support for traits and associated types
  * rustdoc: Add highlighting for comments in items declaration
