rust-lang/rust (rust)

`v1.96.0`

Compare Source

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

Language

Compiler

Libraries

Stabilized APIs

Cargo

Allow a dependency to specify both a git repository and an alternate registry. Just like with crates.io, the git repository will be used locally, but the registry version will be used when published.
Added target.'cfg(..)'.rustdocflags support in configuration.
Fixed CVE-2026-5222 and CVE-2026-5223.

Rustdoc

Deprecation notes are now rendered like any other documentation. Previously they used the css white-space: pre-wrap; property and stripped any <p> elements from the rendered html, however this caused issues and unintuitive behavior. The new behavior should be more predictable, however some multi-line deprecation notes will now be rendered as as single lines. If this is undesirable, you can use the standard markdown method of forcing a linebreak, which is two spaces followed by a newline ("\n").
Don't emit rustdoc missing_doc_code_examples lint on impl items
Separate methods and associated functions in sidebar

Compatibility Notes

Fix layout of #[repr(Int)] enums in some edge cases involving fields of uninhabited zero-sized types
Prevent unsize-coercing into Pin<Foo> where Foo doesn't implement Deref. Some such coercions were previously allowed, but produce a type with no useful public API.
rustc: Stop passing --allow-undefined on wasm targets
Gate the accidentally stabilized #![reexport_test_harness_main] attribute
Error on return-position-impl-trait-in-traits whose types are too private
Report the uninhabited_static lint in dependencies and make it deny-by-default
Distributed builds now contain non-split debuginfo for windows-gnu
This appears to improve the quality of backtraces. This change has no effect on the defaults for the output of rustc/cargo on these targets.
Check const generic arguments are correctly typed in more positions
Remove -Csoft-float
Importing structs with ::{self [as name]}, e.g., struct S {}; use S::{self as Other};, is now no longer permitted because {self} imports require a module parent.
For export_name, link_name, and link_section attributes, if multiple of the same attribute is present, the first one now takes precedence.
Update the minimum external LLVM to 21
On avr targets, C's double type is 32-bit by default, so change c_double to f32 on avr targets to match. This is a breaking change, but necessary to make c_double match C's double.
BTreeMap::append() was optimized, which may now cause panics for types with incorrect Ord impls

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.
