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 lint in order to prevent incoherent state, eg. windows cfg active but target is Linux based. The appropriate rustc flag should be used instead.
• The standard library has a new implementation of binary_search which is significantly improves performance (#​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. 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.
• 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

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

v1.81

Compare Source

==========================

Language

• Abort on uncaught panics in extern "C" functions.
• Fix ambiguous cases of multiple & in elided self lifetimes.
• Stabilize #[expect] for lints (RFC 2383), like #[allow] with a warning if the lint is not fulfilled.
• Change method resolution to constrain hidden types instead of rejecting method candidates.
• Bump elided_lifetimes_in_associated_constant to deny.
• offset_from: always allow pointers to point to the same address.
• Allow constraining opaque types during subtyping in the trait system.
• Allow constraining opaque types during various unsizing casts.
• Deny keyword lifetimes pre-expansion.

Compiler

• Make casts of pointers to trait objects stricter.
• Check alias args for well-formedness even if they have escaping bound vars.
• Deprecate no-op codegen option -Cinline-threshold=....
• Re-implement a type-size based limit.
• Properly account for alignment in transmute size checks.
• Remove the box_pointers lint.
• Ensure the interpreter checks bool/char for validity when they are used in a cast.
• Improve coverage instrumentation for functions containing nested items.
• Target changes:
  • Add Tier 3 no_std Xtensa targets: xtensa-esp32-none-elf, xtensa-esp32s2-none-elf, xtensa-esp32s3-none-elf
  • Add Tier 3 std Xtensa targets: xtensa-esp32-espidf, xtensa-esp32s2-espidf, xtensa-esp32s3-espidf
  • Add Tier 3 i686 Redox OS target: i686-unknown-redox
  • Promote arm64ec-pc-windows-msvc to Tier 2.
  • Promote loongarch64-unknown-linux-musl to Tier 2 with host tools.
  • Enable full tools and profiler for LoongArch Linux targets.
  • Unconditionally warn on usage of wasm32-wasi. (see compatibility note below)
  • Refer to Rust's [platform support page][platform-support-doc] for more information on Rust's tiered platform support.

Libraries

• Split core's PanicInfo and std's PanicInfo. (see compatibility note below)
• Generalize {Rc,Arc}::make_mut() to unsized types.
• Replace sort implementations with stable driftsort and unstable ipnsort. All slice::sort* and slice::select_nth* methods are expected to see significant performance improvements. See the research project for more details.
• Document behavior of create_dir_all with respect to empty paths.
• Fix interleaved output in the default panic hook when multiple threads panic simultaneously.

Stabilized APIs

• core::error
• hint::assert_unchecked
• fs::exists
• AtomicBool::fetch_not
• Duration::abs_diff
• IoSlice::advance
• IoSlice::advance_slices
• IoSliceMut::advance
• IoSliceMut::advance_slices
• PanicHookInfo
• PanicInfo::message
• PanicMessage

These APIs are now stable in const contexts:

• char::from_u32_unchecked (function)
• char::from_u32_unchecked (method)
• CStr::count_bytes
• CStr::from_ptr

Cargo

• Generated .cargo_vcs_info.json is always included, even when --allow-dirty is passed.
• Disallow package.license-file and package.readme pointing to non-existent files during packaging.
• Disallow passing --release/--debug flag along with the --profile flag.
• Remove lib.plugin key support in Cargo.toml. Rust plugin support has been deprecated for four years and was removed in 1.75.0.

Compatibility Notes

• Usage of the wasm32-wasi target will now issue a compiler warning and request users switch to the wasm32-wasip1 target instead. Both targets are the same, wasm32-wasi is only being renamed, and this change to the WASI target is being done to enable removing wasm32-wasi in January 2025.

• We have renamed std::panic::PanicInfo to std::panic::PanicHookInfo. The old name will continue to work as an alias, but will result in a deprecation warning starting in Rust 1.82.0.

  core::panic::PanicInfo will remain unchanged, however, as this is now a different type.

  The reason is that these types have different roles: std::panic::PanicHookInfo is the argument to the panic hook in std context (where panics can have an arbitrary payload), while core::panic::PanicInfo is the argument to the #[panic_handler] in no_std context (where panics always carry a formatted message). Separating these types allows us to add more useful methods to these types, such as std::panic::PanicHookInfo::payload_as_str() and core::panic::PanicInfo::message().

• The new sort implementations may panic if a type's implementation of Ord (or the given comparison function) does not implement a total order as the trait requires. Ord's supertraits (PartialOrd, Eq, and PartialEq) must also be consistent. The previous implementations would not "notice" any problem, but the new implementations have a good chance of detecting inconsistencies, throwing a panic rather than returning knowingly unsorted data.

• In very rare cases, a change in the internal evaluation order of the trait
  solver may result in new fatal overflow errors.

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.

• Add a Rust-for Linux auto CI job to check kernel builds.

• Stabilize global cache data tracking

Misc

• rustdoc: add --test-builder-wrapper arg to support wrappers such as RUSTC_WRAPPER when building doctests

Compatibility Notes

• Many unsafe precondition checks now run for user code with debug assertions enabled
  This change helps users catch undefined behavior in their code, though the details of how much is checked are generally not stable.

• Change equality of higher ranked types to not rely on subtyping
• When called, additionally check bounds on normalized function return type

  This code was accidentally accepted. The fix can break generic code that borrows a value of unknown type,
  as there is currently no way to declare "this type has no interior mutability". In the future, stabilizing
  the Freeze trait will allow proper support for such code.
