Cargo
CARGO_MANIFEST_PATH
environment variable, similar toCARGO_MANIFEST_DIR
but pointing directly to the manifest file.package.autolib
to the manifest, allowing[lib]
auto-discovery to be disabled.Rustdoc
# headers
from the main item's doc comment. This is similar to a third-party feature provided by the rustdoc-search-enhancements browser extension.Compatibility Notes
Warn against function pointers using unsupported ABI strings.
Check well-formedness of the source type's signature in fn pointer casts. This partly closes a soundness hole that comes when casting a function item to function pointer
Use equality instead of subtyping when resolving type dependent paths.
Linking on macOS now correctly includes Rust's default deployment target. Due to a linker bug, you might have to pass
MACOSX_DEPLOYMENT_TARGET
or fix your#[link]
attributes to point to the correct frameworks. See #129369.Rust will now correctly raise an error for
repr(Rust)
written on non-struct
/enum
/union
items, since it previous did not have any effect.The future incompatibility lint
deprecated_cfg_attr_crate_type_name
has been made into a hard error. It was used to deny usage of#![crate_type]
and#![crate_name]
attributes in#![cfg_attr]
, which required a hack in the compiler to be able to change the used crate type and crate name after cfg expansion.Users can use
--crate-type
instead of#![cfg_attr(..., crate_type = "...")]
and--crate-name
instead of#![cfg_attr(..., crate_name = "...")]
when runningrustc
/cargo rustc
on the command line.Use of those two attributes outside of
#![cfg_attr]
continue to be fully supported.Until now, paths into the sysroot were always prefixed with
/rustc/$hash
in diagnostics, codegen, backtrace, e.g.RFC 3127 said
#129687 implements this behaviour, when
rust-src
is present at compile time,rustc
replaces/rustc/$hash
with a real path into the localrust-src
component with best effort.To sanitize this, users must explicitly supply
--remap-path-prefix=<path to rust-src>=foo
or not have therust-src
component installed.The allow-by-default
missing_docs
lint used to disable itself when invoked throughrustc --test
/cargo test
, resulting in#[expect(missing_docs)]
emitting false positives due to the expectation being wrongly unfulfilled. This behavior has now been removed, which allows#[expect(missing_docs)]
to be fulfilled in all scenarios, but will also report newmissing_docs
diagnostics for publicly reachable#[cfg(test)]
items, integration test crate-level documentation, and publicly reachable items in integration tests.The
armv8r-none-eabihf
target now uses the Armv8-R required set of floating-point features.Fix a soundness bug where rustc wouldn't detect unconstrained higher-ranked lifetimes in a
dyn Trait
's associated types that occur due to supertraits.Update the minimum external LLVM version to 18.
Remove
aarch64-fuchsia
andx86_64-fuchsia
target aliases in favor ofaarch64-unknown-fuchsia
andx86_64-unknown-fuchsia
respectively.The ABI-level exception class of a Rust panic is now encoded with native-endian bytes, so it is legible in hex dumps.
Visual Studio 2013 is no longer supported for MSVC targets.
The sysroot no longer contains the
std
dynamic library in its top-levellib/
dir.Configuration
