Introducing Rust 1.80: Lazy Types, Ranged Patterns, and More
Are you a developer looking to stay on top of the latest updates in the programming world? If so, you’ll be excited to hear about the release of Rust 1.80, the newest version of the popular memory-safe programming language. This latest update brings some exciting new features that are sure to enhance your coding experience.
One of the standout features of Rust 1.80 is the introduction of “lazy” types, including LazyCell and LazyLock. These types allow for the delayed initialization of data until their first access, providing more flexibility and efficiency in your code. LazyLock is the thread-safe option, perfect for static values, while LazyCell lacks thread synchronization but can still be used in thread_local! statics.
In addition to the new lazy types, Rust 1.80 also introduces exclusive endpoints for ranged patterns, making pattern matching more precise and less error-prone. The exhaustiveness checking has been improved to better detect gaps in pattern matching, and new lints have been added to help developers switch between exclusive and inclusive patterns.
Furthermore, Cargo 1.80 now enables the –check-cfg flag for all cfg names and values, providing more comprehensive checks during the build process. This update also stabilizes numerous APIs, ensuring a more reliable and consistent development experience.
Overall, Rust 1.80 is a significant update that brings valuable enhancements to the language. If you’re a Rust developer, be sure to update to the latest version to take advantage of these new features and improvements. Happy coding!
