[`std::num::ParseIntError::kind`](https://doc.rust-lang.org/nightly/std/num/struct.ParseIntError.html#method.kind) <a id="1.82.0-Cargo"></a> ## 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 ([#​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) <a id="1.82.0-Internal-Changes"></a> ## 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. - [Update to LLVM 19](rust-lang/rust#127513) </details> --- ### Configuration 📅 **Schedule**: Branch creation - At any time (no schedule defined), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.

[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. - [Update to LLVM 19] (rust-lang/rust#127513)
