.Rust Toolset rebased to version 1.88.0 RHEL 9.7 is distributed with Rust Toolset in version 1.88.0. This update includes the following notable enhancements:  * Rust 2024 Edition is now stable. This is a major opt-in release that enables significant language changes and is the largest edition released to date.  * Leverage the 2024 Edition with `let` chains, allowing fluent `&&`-chaining of `let` statements within `if` and `while` conditions to reduce nesting and improve readability.  * For high-performance computing, when you enable target features, you can call multiple `std::arch` intrinsics directly in safe Rust, which gives you direct access to specific CPU features.  * `async` closures are now supported, providing first-class solutions for asynchronous programming. These closures allow borrowing from captures and properly express higher-ranked function signatures with the AsyncFn traits.  * Trait upcasting allows coercing a reference to a trait object to a reference of its supertrait, simplifying common patterns, especially with the `Any` trait.  * Cargo now automatically cleans its cache, removing old downloaded files not accessed in 1-3 months, which helps manage disk space. Rust Toolset is a rolling Application Stream, and Red Hat only supports the latest version.
