.Rust Toolset rebased to version 1.84.0 Rust Toolset has been updated to version 1.84.0. Notable enhancements since the previously available version 1.79.0 include: * New `LazyCell` and `LazyLock` types delay initialization until first use.   These extend the earlier `OnceCell` and `OnceLock` types with the   initialization function included directly in each instance. * New sort implementations in the standard library improve runtime performance   and compile times. They also try to detect cases where a comparator isn't   producing a total order, making that panic instead of returning unsorted data. * Precise capturing for opaque return types: new `use<..>` syntax specifies the   generic parameters and lifetimes used in an `impl Trait` return type. * Many new features for `const` code, including floating point support, `const`   immediates for inline assembly, references to statics, and mutable references   and pointers. * Many new features for `unsafe` code, including strict provenance APIs, `&raw`   pointer syntax, safely addressing statics, and declaring safe items in unsafe   `extern` blocks. * Version-aware Cargo dependency resolver: if a dependency crate specifies its   minimum supported `rust-version`, this is taken into consideration when Cargo   resolves the dependency graph, rather than greedily choosing the latest   semver-compatible crate version available. Compatibility notes: * WASI target change: `rust-std-static-wasm32-wasi` is now   replaced by `rust-std-static-wasm32-wasip1`, which is used   as `--target wasm32-wasip1` on the command line.   See https://blog.rust-lang.org/2024/04/09/updates-to-rusts-wasi-targets.html * Split panic hook and panic handler arguments: `core::panic::PanicInfo`   and `std::panic::PanicInfo` are now different types. * Abort on uncaught panics in `extern "C"` functions -- it is now required to   use `extern "C-unwind"` to allow unwinding across ABI boundaries. Rust Toolset is a rolling Application Stream, and only the latest version is supported.
