Rust is a system programming language that aims to provide memory safety, concurrency, and performance with a focus on zero cost abstractions, minimal runtime, and improved productivity. Coursera's Rust catalogue teaches you about this unique programming approach that eliminates common bugs caused by null pointers, dangling pointers, and data races. You'll learn the core concepts such as ownership, borrowing, and lifetimes, as well as advanced features like async programming, macros, and concurrency. Further, the catalogue will introduce you to Rust's ecosystem and its package manager, Cargo. Ultimately, you'll be able to write more reliable and efficient code for system-level applications and complex multi-threaded software.
