Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @davidtwco (or someone else) soon.

Please see the contribution instructions for more information.

Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with @rustbot label +T-libs-api -T-libs to tag it appropriately. If this PR contains changes to any unstable APIs please edit the PR description to add a link to the relevant API Change Proposal or create one if you haven't already. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

  • Stabilizing library features
  • Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
  • Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
  • Changing public documentation in ways that create new stability guarantees
  • Changing observable runtime behavior of library APIs

LGTM, but will hand-off to someone from t-libs to double-check.

wip-sync pushed a commit to NetBSD/pkgsrc-wip that referenced this pull request Apr 24, 2023
Pkgsrc changes:
 * Adjust patches and cargo checksums to new versions.
 * Sadly, the patch to reduce the cargo verbosity no longer applies,
   so I've asked upstream about the proper way to get the old result.
   (so the build log becomes Quite Bloated for now).

Upstream changes:

Version 1.69.0 (2023-04-20)
==========================

Language
--------

- [Deriving built-in traits on packed structs works with `Copy` fields.]
  (rust-lang/rust#104429)
- [Stabilize the `cmpxchg16b` target feature on x86 and x86_64.]
  (rust-lang/rust#106774)
- [Improve analysis of trait bounds for associated types.]
  (rust-lang/rust#103695)
- [Allow associated types to be used as union fields.]
  (rust-lang/rust#106938)
- [Allow `Self: Autotrait` bounds on dyn-safe trait methods.]
  (rust-lang/rust#107082)
- [Treat `str` as containing `[u8]` for auto trait purposes.]
  (rust-lang/rust#107941)

Compiler
--------

- [Upgrade `*-pc-windows-gnu` on CI to mingw-w64 v10 and GCC 12.2.]
  (rust-lang/rust#100178)
- [Rework min_choice algorithm of member constraints.]
  (rust-lang/rust#105300)
- [Support `true` and `false` as boolean flags in compiler arguments.]
  (rust-lang/rust#107043)
- [Default `repr(C)` enums to `c_int` size.]
  (rust-lang/rust#107592)

Libraries
---------

- [Implement the unstable `DispatchFromDyn` for cell types, allowing
  downstream experimentation with custom method receivers.]
  (rust-lang/rust#97373)
- [Document that `fmt::Arguments::as_str()` may return `Some(_)`
  in more cases after optimization, subject to change.]
  (rust-lang/rust#106823)
- [Implement `AsFd` and `AsRawFd` for `Rc`.]
  (rust-lang/rust#107317)

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

- [`CStr::from_bytes_until_nul`]
  (https://doc.rust-lang.org/stable/core/ffi/struct.CStr.html#method.from_bytes_until_nul)
- [`core::ffi::FromBytesUntilNulError`]
  (https://doc.rust-lang.org/stable/core/ffi/struct.FromBytesUntilNulError.html)

These APIs are now stable in const contexts:

- [`SocketAddr::new`]
  (https://doc.rust-lang.org/stable/std/net/enum.SocketAddr.html#method.new)
- [`SocketAddr::ip`]
  (https://doc.rust-lang.org/stable/std/net/enum.SocketAddr.html#method.ip)
- [`SocketAddr::port`]
  (https://doc.rust-lang.org/stable/std/net/enum.SocketAddr.html#method.port)
- [`SocketAddr::is_ipv4`]
  (https://doc.rust-lang.org/stable/std/net/enum.SocketAddr.html#method.is_ipv4)
- [`SocketAddr::is_ipv6`]
  (https://doc.rust-lang.org/stable/std/net/enum.SocketAddr.html#method.is_ipv6)
- [`SocketAddrV4::new`]
  (https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV4.html#method.new)
- [`SocketAddrV4::ip`]
  (https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV4.html#method.ip)
- [`SocketAddrV4::port`]
  (https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV4.html#method.port)
- [`SocketAddrV6::new`]
  (https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV6.html#method.new)
- [`SocketAddrV6::ip`]
  (https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV6.html#method.ip)
- [`SocketAddrV6::port`]
  (https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV6.html#method.port)
- [`SocketAddrV6::flowinfo`]
  (https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV6.html#method.flowinfo)
- [`SocketAddrV6::scope_id`]
  (https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV6.html#method.scope_id)

Cargo
-----

- [Cargo now suggests `cargo fix` or `cargo clippy --fix` when compilation warnings are auto-fixable.]
  (rust-lang/cargo#11558)
- [Cargo now suggests `cargo add` if you try to install a library crate.]
  (rust-lang/cargo#11410)
- [Cargo now sets the `CARGO_BIN_NAME` environment variable also for binary examples.]
  (rust-lang/cargo#11705)

Rustdoc
-----

- [Vertically compact trait bound formatting.]
  (rust-lang/rust#102842)
- [Only include stable lints in `rustdoc::all` group.]
  (rust-lang/rust#106316)
- [Compute maximum Levenshtein distance based on the query.]
  (rust-lang/rust#107141)
- [Remove inconsistently-present sidebar tooltips.]
  (rust-lang/rust#107490)
- [Search by macro when query ends with `!`.]
  (rust-lang/rust#108143)

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

- [The `rust-analysis` component from `rustup` now only contains
  a warning placeholder.]
  (rust-lang/rust#101841) This was primarily
  intended for RLS, and the corresponding `-Zsave-analysis` flag
  has been removed from the compiler as well.
- [Unaligned references to packed fields are now a hard error.]
  (rust-lang/rust#102513) This has been
  a warning since 1.53, and denied by default with a future-compatibility
  warning since 1.62.
- [Update the minimum external LLVM to 14.]
  (rust-lang/rust#107573)
- [Cargo now emits errors on invalid characters in a registry token.]
  (rust-lang/cargo#11600)
- [When `default-features` is set to false of a workspace dependency,
  and an inherited dependency of a member has `default-features =
  true`, Cargo will enable default features of that dependency.]
  (rust-lang/cargo#11409)
- [Cargo denies `CARGO_HOME` in the `[env]` configuration table.
  Cargo itself doesn't pick up this value, but recursive calls to
  cargo would, which was not intended.]
  (rust-lang/cargo#11644)
- [Debuginfo for build dependencies is now off if not explicitly
  set. This is expected to improve the overall build time.]

  (rust-lang/cargo#11252)

Internal Changes
----------------

These changes do not affect any public interfaces of Rust, but they represent
significant improvements to the performance or internals of rustc and related
tools.

- [Move `format_args!()` into AST (and expand it during AST lowering)]
