Rust Programming in easy steps introduces all the features of the Rust programming language, using worked example programs. Rust is still an immature language and sees a major release every six years. Rust 2024 is expected to be released in February 2025, and is the version of the language that this book will deal with. The language differences are slight. Of greater concern is the library of crates that support more advanced features. Many of these are either not in place or not stable enough to be relied on. In particular, no one crate has emerged that provides a desktop GUI interface.
