Rust is a multi-paradigm, general-purpose programming language that emphasizes performance, type safety, and concurrency. In 2023, Rust 1.74.0  introduced  several new features. Lint Configuration via Cargo is suggested in RFC 3389, the Cargo.toml manifest file now supports adding lint configurations for reports from the compiler or other tools. These settings, with workspace = true, can also be configured in [workspace.lints] and inherited like many other workspace settings. Cargo will track changes to these settings to determine which crates need rebuilding.

Rust 1.74.0 compiler now allows referencing Self and associated types in opaque return types, such as in async fn and -> impl Trait. This feature brings Rust closer to working the way you expect, even if you’re unfamiliar with terms like “projections.”
