![]() ![]() Document that fmt::Arguments::as_str() may return Some(_) in more cases after optimization, subject to change.Implement the unstable DispatchFromDyn for cell types, allowing downstream experimentation with custom method receivers.Support true and false as boolean flags in compiler arguments. ![]() Rework min_choice algorithm of member constraints.Upgrade *-pc-windows-gnu on CI to mingw-w64 v10 and GCC 12.2.Treat str as containing for auto trait purposes.Allow Self: Autotrait bounds on dyn-safe trait methods.Allow associated types to be used as union fields.Improve analysis of trait bounds for associated types.Stabilize the cmpxchg16b target feature on x86 and x86_64.Deriving built-in traits on packed structs works with Copy fields.Use SipHash-1-3 instead of SipHash-2-4 for StableHasher.Significant improvements to the performance or internals of rustc and related These changes do not affect any public interfaces of Rust, but they represent This catches undefined behavior at runtime, and may cause existing code to fail. Insert alignment checks for pointer dereferences as debug assertions.This may cause incompatibility with older execution environments. WebAssembly targets enable sign-ext and mutable-globals features in codegen.Prevent stable libtest from supporting -Zunstable-options.Accurately show status when downgrading dependencies.Make sparse the default protocol for crates.io.std::os::unix::net::UnixListener::bind_addr.std::os::unix::net::UnixDatagram::send_to_addr.std::os::unix::net::UnixDatagram::connect_addr.std::os::unix::net::UnixDatagram::bind_addr.Detect uninhabited types early in const eval.Make unused_allocation lint against Box::new too.( -Cdebuginfo=line-tables-only), which may eventually become the default for -Cdebuginfo=1. This provides a smaller version of debuginfo for cases that only need line number information Extend -Cdebuginfo with new options and named aliases.Perform const and unsafe checking for expressions in let _ = expr position.Properly allow macro expanded format_args invocations to uses captures. ![]()
