## Cargo

-   [feat: Add `info` cargo subcommand](rust-lang/cargo#14141)

<a id="1.82.0-Compatibility-Notes"></a>

## Compatibility Notes

-   We now [disallow setting some built-in cfgs via the command-line](rust-lang/rust#126158) 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 ([#&#8203;128254](rust-lang/rust#128254)). 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.
-   [illumos/Solaris now sets `MSG_NOSIGNAL` when writing to sockets](rust-lang/rust#128259). This avoids killing the process with SIGPIPE when writing to a closed socket, which matches the existing behavior on other UNIX targets.
-   [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.](rust-lang/rust#128400)
-   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-lang/rust#128511).

## 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.

Cargo
-----
- [feat: Add `info` cargo subcommand]
  (rust-lang/cargo#14141)

Compatibility Notes
-------------------
 - We now [disallow setting some built-in cfgs via the
   command-line](rust-lang/rust#126158) 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
  ([#128254](rust-lang/rust#128254)). 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.

- [illumos/Solaris now sets `MSG_NOSIGNAL` when writing to
  sockets](rust-lang/rust#128259). This avoids
  killing the process with SIGPIPE when writing to a closed socket,
  which matches the existing behavior on other UNIX targets.

- [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.]
  (rust-lang/rust#128400)

- 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-lang/rust#128511).
- [Rust now raises unsafety errors for union patterns in parameter-position]
  (rust-lang/rust#130531)

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.

Pkgsrc changes:
 * Adapt patches, apply to new vendored crates where needed.
 * Back-port rust pull request 130110, "make dist vendoring configurable"
 * Disable "dist vendoring", otherwise cargo would try to access
   the network during the build phase.
 * Dial down the verbosity of the build by dropping -v argument to x.py.

Cargo
-----
- [feat: Add `info` cargo subcommand]
  (rust-lang/cargo#14141)

Compatibility Notes
-------------------
 - We now [disallow setting some built-in cfgs via the
   command-line](rust-lang/rust#126158) 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
  ([#128254](rust-lang/rust#128254)). 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.

- [illumos/Solaris now sets `MSG_NOSIGNAL` when writing to
  sockets](rust-lang/rust#128259). This avoids
  killing the process with SIGPIPE when writing to a closed socket,
  which matches the existing behavior on other UNIX targets.

- [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.]
  (rust-lang/rust#128400)

- 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-lang/rust#128511).
- [Rust now raises unsafety errors for union patterns in parameter-position]
  (rust-lang/rust#130531)

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.

Stabilize `#![feature(precise_capturing_in_traits)]`

# Precise capturing (`+ use<>` bounds) in traits - Stabilization Report

Fixes rust-lang#130044.

## Stabilization summary

This report proposes the stabilization of `use<>` precise capturing bounds in return-position impl traits in traits (RPITITs). This completes a missing part of [RFC 3617 "Precise capturing"].

Precise capturing in traits was not ready for stabilization when the first subset was proposed for stabilization (namely, RPITs on free and inherent functions - rust-lang#127672) since this feature has a slightly different implementation, and it hadn't yet been implemented or tested at the time. It is now complete, and the type system implications of this stabilization are detailed below.

## Motivation

Currently, RPITITs capture all in-scope lifetimes, according to the decision made in the ["lifetime capture rules 2024" RFC](https://rust-lang.github.io/rfcs/3498-lifetime-capture-rules-2024.html#return-position-impl-trait-in-trait-rpitit). However, traits can be designed such that some lifetimes in arguments may not want to be captured. There is currently no way to express this.

## Major design decisions since the RFC

No major decisions were made. This is simply an extension to the RFC that was understood as a follow-up from the original stabilization.

## What is stabilized?

Users may write `+ use<'a, T>` bounds on their RPITITs. This conceptually modifies the desugaring of the RPITIT to omit the lifetimes that we would copy over from the method. For example,

```rust
trait Foo {
    fn method<'a>(&'a self) -> impl Sized;

    // ... desugars to something like:
    type RPITIT_1<'a>: Sized;
    fn method_desugared<'a>(&'a self) -> Self::RPITIT_1<'a>;

    // ... whereas with precise capturing ...
    fn precise<'a>(&'a self) -> impl Sized + use<Self>;

    // ... desugars to something like:
    type RPITIT_2: Sized;
    fn precise_desugared<'a>(&'a self) -> Self::RPITIT_2;
}
```

And thus the GAT doesn't name `'a`. In the compiler internals, it's not implemented exactly like this, but not in a way that users should expect to be able to observe.

#### Limitations on what generics must be captured

Currently, we require that all generics from the trait (including the `Self`) type are captured. This is because the generics from the trait are required to be *invariant* in order to do associated type normalization.

And like regular precise capturing bounds, all type and const generics in scope must be captured.

Thus, only the in-scope method lifetimes may be relaxed with this syntax today.

## What isn't stabilized? (a.k.a. potential future work)

See section above. Relaxing the requirement to capture all type and const generics in scope may be relaxed when rust-lang#130043 is implemented, however it currently interacts with some underexplored corners of the type system (e.g. unconstrained type bivariance) so I don't expect it to come soon after.

## Implementation summary

This functionality is implemented analogously to the way that *opaque type* precise capturing works.

Namely, we currently use *variance* to model the capturedness of lifetimes. However, since RPITITs are anonymous GATs instead of opaque types, we instead modify the type relation of GATs to consider variances for RPITITs (along with opaque types which it has done since rust-lang#103491).

https://github.com/rust-lang/rust/blob/30f168ef811aec63124eac677e14699baa9395bd/compiler/rustc_middle/src/ty/util.rs#L954-L976

https://github.com/rust-lang/rust/blob/30f168ef811aec63124eac677e14699baa9395bd/compiler/rustc_type_ir/src/relate.rs#L240-L244

Using variance to model capturedness is an implementation detail, and in the future it would be desirable if opaques and RPITITs simply did not include the uncaptured lifetimes in their generics. This can be changed in a forwards-compatible way, and almost certainly would not be observable by users (at least not negatively, since it may indeed fix some bugs along the way).

## Tests

* Test that the lifetime isn't actually captured: `tests/ui/impl-trait/precise-capturing/rpitit.rs` and `tests/ui/impl-trait/precise-capturing/rpitit-outlives.rs` and `tests/ui/impl-trait/precise-capturing/rpitit-outlives-2.rs`.
* Technical test for variance computation: `tests/ui/impl-trait/in-trait/variance.rs`.
* Test that you must capture all trait generics: `tests/ui/impl-trait/precise-capturing/forgot-to-capture-type.rs`.
* Test that you cannot capture more than what the trait specifies: `tests/ui/impl-trait/precise-capturing/rpitit-captures-more-method-lifetimes.rs` and `tests/ui/impl-trait/precise-capturing/rpitit-impl-captures-too-much.rs`.
* Undercapturing (refinement) lint: `tests/ui/impl-trait/in-trait/refine-captures.rs`.

### What other unstable features may be exposed by this feature?

I don't believe that this exposes any new unstable features indirectly.

## Remaining bugs and open issues

Not aware of any open issues or bugs.

## Tooling support

Rustfmt: ✅ Supports formatting `+ use<>` everywhere.

Clippy: ✅ No support needed, unless specific clippy lints are impl'd to care for precise capturing itself.

Rustdoc: ✅ Rendering `+ use<>` precise capturing bounds is supported.

Rust-analyzer: ✅ Parser support, and then lifetime support isn't needed rust-lang#138128 (comment) (previous: ~~:question: There is parser support, but I am unsure of rust-analyzer's level of support for RPITITs in general.~~)
