Rust 1.79 has been released with inline const expressions, simplified bounds, and more

The Rust team has released Rust 1.79, bringing several key enhancements and new features. One significant update is the stabilization of const { … } blocks in expression positions. This feature allows developers to enter a const context without additional declarations, use in-scope generics, and infer types, thereby improving the efficiency of inline code snippets.

Rust 1.79 also introduces the stabilization of associated item bounds syntax. This enhancement allows developers to place bounds in associated type positions within other bounds, eliminating the need for an extra generic type to constrain the associated type. This change simplifies code and reduces unnecessary constraints.

Furthermore, the release includes automatic lifetime extension for temporaries immediately referenced in match and if constructs, aligning their behavior with lifetime extension in block constructs. The standard library is now compiled with -Cforce-frame-pointers=yes, which makes profiling easier for downstream users. The release also features numerous stabilized APIs, various changes, and bug fixes.
