rust-lang/rust (rust-lang/rust)

v1.93.0

Compare Source

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

Language

• Stabilize several s390x vector-related target features and the is_s390x_feature_detected! macro
• Stabilize declaration of C-style variadic functions for the system ABI
• Emit error when using some keyword as a cfg predicate
• Stabilize asm_cfg
• During const-evaluation, support copying pointers byte-by-byte
• LUB coercions now correctly handle function item types, and functions with differing safeties
• Allow const items that contain mutable references to static (which is very unsafe, but not always UB)
• Add warn-by-default const_item_interior_mutations lint to warn against calls which mutate interior mutable const items
• Add warn-by-default function_casts_as_integer lint

Compiler

• Stabilize -Cjump-tables=bool. The flag was previously called -Zno-jump-tables.

Platform Support

• Promote riscv64a23-unknown-linux-gnu to Tier 2 (without host tools)

Refer to Rust's platform support page
for more information on Rust's tiered platform support.

Libraries

• Stop internally using specialization on the Copy trait as it is unsound in the presence of lifetime dependent Copy implementations. This may result in some performance regressions as some standard library APIs may now call Clone::clone instead of performing bitwise copies
• Allow the global allocator to use thread-local storage and std::thread::current()
• Make BTree::append not update existing keys when appending an entry which already exists
• Don't require T: RefUnwindSafe for vec::IntoIter<T>: UnwindSafe

Stabilized APIs

• <[MaybeUninit<T>]>::assume_init_drop
• <[MaybeUninit<T>]>::assume_init_ref
• <[MaybeUninit<T>]>::assume_init_mut
• <[MaybeUninit<T>]>::write_copy_of_slice
• <[MaybeUninit<T>]>::write_clone_of_slice
• String::into_raw_parts
• Vec::into_raw_parts
• <iN>::unchecked_neg
• <iN>::unchecked_shl
• <iN>::unchecked_shr
• <uN>::unchecked_shl
• <uN>::unchecked_shr
• <[T]>::as_array
• <[T]>::as_mut_array
• <*const [T]>::as_array
• <*mut [T]>::as_mut_array
• VecDeque::pop_front_if

• Duration::from_nanos_u128
• char::MAX_LEN_UTF8
• char::MAX_LEN_UTF16
• std::fmt::from_fn
• std::fmt::FromFn

Cargo

• Enable CARGO_CFG_DEBUG_ASSERTIONS in build scripts based on profile
• In cargo tree, support long forms for --format variables
• Add --workspace to cargo clean

Rustdoc

• Remove #![doc(document_private_items)]
• Include attribute and derive macros in search filters for "macros"
• Include extern crates in search filters for import
• Validate usage of crate-level doc attributes. This means if any of html_favicon_url, html_logo_url, html_playground_url, issue_tracker_base_url, or html_no_source either has a missing value, an unexpected value, or a value of the wrong type, rustdoc will emit the deny-by-default lint rustdoc::invalid_doc_attributes.

Compatibility Notes

• Introduce pin_v2 into the builtin attributes namespace
• Update bundled musl to 1.2.5
• On Emscripten, the unwinding ABI used when compiling with panic=unwind was changed from the JS exception handling ABI to the wasm exception handling ABI. If linking C/C++ object files with Rust objects, -fwasm-exceptions must be passed to the linker now. On nightly Rust, it is possible to get the old behavior with -Zwasm-emscripten-eh=false -Zbuild-std, but it will be removed in a future release.
• The #[test] attribute, used to define tests, was previously ignored in various places where it had no meaning (e.g on trait methods or types). Putting the #[test] attribute in these places is no longer ignored, and will now result in an error; this may also result in errors when generating rustdoc. Error when test attribute is applied to structs
• Cargo now sets the CARGO_CFG_DEBUG_ASSERTIONS environment variable in more situations. This will cause crates depending on static-init versions 1.0.1 to 1.0.3 to fail compilation with "failed to resolve: use of unresolved module or unlinked crate parking_lot". See the linked issue for details.
• User written types in the offset_of! macro are now checked to be well formed.
• cargo publish no longer emits .crate files as a final artifact for user access when the build.build-dir config is unset
• Upgrade the deref_nullptr lint from warn-by-default to deny-by-default
• Add future-incompatibility warning for ... function parameters without a pattern outside of extern blocks
• Introduce future-compatibility warning for repr(C) enums whose discriminant values do not fit into a c_int or c_uint
• Introduce future-compatibility warning against ignoring repr(C) types as part of repr(transparent)

v1.92.0

Compare Source

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

Language

• Document MaybeUninit representation and validity
• Allow &raw [mut | const] for union field in safe code
• Prefer item bounds of associated types over where-bounds for auto-traits and Sized
• Do not materialize X in [X; 0] when X is unsizing a const
• Support combining #[track_caller] and #[no_mangle] (requires every declaration specifying #[track_caller] as well)
• Make never type lints never_type_fallback_flowing_into_unsafe and dependency_on_unit_never_type_fallback deny-by-default
• Allow specifying multiple bounds for same associated item, except in trait objects
• Slightly strengthen higher-ranked region handling in coherence
• The unused_must_use lint no longer warns on Result<(), Uninhabited> (for instance, Result<(), !>), or ControlFlow<Uninhabited, ()>. This avoids having to check for an error that can never happen.

Compiler

• Make mips64el-unknown-linux-muslabi64 link dynamically
• Remove current code for embedding command-line args in PDB
  Command-line information is typically not needed by debugging tools, and the removed code
  was causing problems for incremental builds even on targets that don't use PDB debuginfo.

Libraries

• Specialize Iterator::eq{_by} for TrustedLen iterators
• Simplify Extend for tuples
• Added details to Debug for EncodeWide.
• iter::Repeat::last and count will now panic, rather than looping infinitely.

Stabilized APIs

• NonZero<u{N}>::div_ceil
• Location::file_as_c_str
• RwLockWriteGuard::downgrade
• Box::new_zeroed
• Box::new_zeroed_slice
• Rc::new_zeroed
• Rc::new_zeroed_slice
• Arc::new_zeroed
• Arc::new_zeroed_slice
• btree_map::Entry::insert_entry
• btree_map::VacantEntry::insert_entry

• impl Extend<proc_macro::Literal> for proc_macro::TokenStream
• impl Extend<proc_macro::Punct> for proc_macro::TokenStream
• impl Extend<proc_macro::Ident> for proc_macro::TokenStream

These previously stable APIs are now stable in const contexts:

• <[_]>::rotate_left
• <[_]>::rotate_right

Cargo

• Added a new chapter to the Cargo book, "Optimizing Build Performance".

Rustdoc

• If a trait item appears in rustdoc search, hide the corresponding impl items. Previously a search for "last" would show both Iterator::last as well as impl methods like std::vec::IntoIter::last. Now these impl methods will be hidden, freeing up space for inherent methods like BTreeSet::last.
• Relax rules for identifiers in search. Previously you could only search for identifiers that were valid in rust code, now searches only need to be valid as part of an identifier. For example, you can now perform a search that starts with a digit.

Compatibility Notes

• Fix backtraces with -C panic=abort on Linux by generating unwind tables by default. Build with -C force-unwind-tables=no to keep omitting unwind tables.

• As part of the larger effort refactoring compiler built-in attributes and their diagnostics, the future-compatibility lint invalid_macro_export_arguments is upgraded to deny-by-default and will be reported in dependencies too.
• Update the minimum external LLVM to 20
• Prevent downstream impl DerefMut for Pin<LocalType>
• Don't apply temporary lifetime extension rules to the arguments of non-extended pin! and formatting macros

v1.91.1

Compare Source

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

• Enable file locking support in illumos. This fixes Cargo not locking the build directory on illumos.
• Fix wasm_import_module attribute cross-crate. This fixes linker errors on WASM targets.

v1.91.0

Compare Source

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

Language

• Lower pattern bindings in the order they're written and base drop order on primary bindings' order
• Stabilize declaration of C-style variadic functions for sysv64, win64, efiapi, and aapcs ABIs.
  This brings these ABIs in line with the C ABI: variadic functions can be declared in extern blocks but not defined.
• Add dangling_pointers_from_locals lint to warn against dangling pointers from local variables
• Upgrade semicolon_in_expressions_from_macros from warn to deny
• Stabilize LoongArch32 inline assembly
• Add warn-by-default integer_to_ptr_transmutes lint against integer-to-pointer transmutes
• Stabilize sse4a and tbm target features
• Add target_env = "macabi" and target_env = "sim" cfgs as replacements for the target_abi cfgs with the same values.

Compiler

• Don't warn on never-to-any as casts as unreachable

Platform Support

• Promote aarch64-pc-windows-gnullvm and x86_64-pc-windows-gnullvm to Tier 2 with host tools.
  Note: llvm-tools and MSI installers are missing but will be added in future releases.
• Promote aarch64-pc-windows-msvc to Tier 1

Refer to Rust's platform support page
for more information on Rust's tiered platform support.

Libraries

• Print thread ID in panic message
• Fix overly restrictive lifetime in core::panic::Location::file return type
• Guarantee parameter order for _by() variants of min / max/ minmax in std::cmp

Cargo

• 🎉 Stabilize build.build-dir.
  This config sets the directory where intermediate build artifacts are stored.
  These artifacts are produced by Cargo and rustc during the build process.
  End users usually won't need to interact with them, and the layout inside
  build-dir is an implementation detail that may change without notice.
  (config doc)
  (build cache doc)
  #​15833
  #​15840
• The --target flag and the build.target configuration can now take literal
  "host-tuple" string, which will internally be substituted by the host
  machine's target triple.
  #​15838
  #​16003
  #​16032

Rustdoc

• In search results, rank doc aliases lower than non-alias items with the same name
• Raw pointers now work in type-based search like references. This means you can now search for things like *const u8 ->, and additionally functions that take or return raw pointers will now display their signature properly in search results.

Compatibility Notes

• Always require coroutine captures to be drop-live
• Apple: Always pass SDK root when linking with cc, and pass it via SDKROOT env var. This should fix linking issues with rustc running inside Xcode. Libraries in /usr/local/lib may no longer be linked automatically, if you develop or use a crate that relies on this, you should explicitly set cargo::rustc-link-search=/usr/local/lib in a build.rs script.
• Relaxed bounds in associated type bound position like in TraitRef<AssocTy: ?Sized> are now correctly forbidden
• Add unstable #[sanitize(xyz = "on|off")] built-in attribute that shadows procedural macros with the same name
• Fix the drop checker being more permissive for bindings declared with let-else
• Be more strict when parsing attributes, erroring on many invalid attributes
  • Error on invalid #[should_panic] attributes
  • Error on invalid #[link] attributes
• Mark all deprecation lints in name resolution as deny-by-default and also report in dependencies
• The lint semicolon_in_expressions_from_macros, for macro_rules! macros in expression position that expand to end in a semicolon (;), is now deny-by-default. It was already warn-by-default, and a future compatibility warning (FCW) that warned even in dependencies. This lint will become a hard error in the future.
• Trait impl modifiers (e.g., unsafe, !, default) in inherent impls are no longer syntactically valid
• Start reporting future breakage for ill_formed_attribute_input in dependencies
• Restrict the scope of temporaries created by the macros pin!, format_args!, write!, and writeln! in if let scrutinees in Rust Edition 2024. This applies Rust Edition 2024's if let temporary scope rules to these temporaries, which previously could live past the if expression regardless of Edition.
• Invalid numeric literal suffixes in tuple indexing, tuple struct indexing, and struct field name positions are now correctly rejected
• Closures marked with the keyword static are now syntactically invalid
• Shebangs inside --cfg and --check-cfg arguments are no longer allowed
• Add future incompatibility lint for temporary lifetime shortening in Rust 1.92

Cargo compatibility notes:

• cargo publish no longer keeps .crate tarballs as final build artifacts
  when build.build-dir is set. These tarballs were previously included due to
  an oversight and are now treated as intermediate artifacts.
  To get .crate tarballs as final artifacts, use cargo package.
  In a future version, this change will apply regardless of build.build-dir.
  #​15910
• Adjust Cargo messages to match rustc diagnostic style.
  This changes some of the terminal colors used by Cargo messages.
  #​15928
• Tools and projects relying on the
  internal details of Cargo's build-dir
  may not work for users changing their build-dir layout.
  For those doing so, we'd recommend proactively testing these cases
  particularly as we are considering changing the default location of the build-dir in the future
  (cargo#16147).
  If you can't migrate off of Cargo's internal details,
  we'd like to learn more about your use case as we prepare to change the layout of the build-dir
  (cargo#15010).
