memory-safe programming language without garbage collection

AI overview

Rust is a modern programming language designed to prevent common computer programming errors—particularly memory-related bugs—without requiring automatic garbage collection to clean up unused data. It matters because it enables programmers to write faster, more reliable software while maintaining safety features that typically require more computational overhead.

Article

Rust is a general-purpose programming language which emphasizes performance, type safety, concurrency, and memory safety.

Rust supports multiple programming paradigms. It was influenced by ideas from functional programming, including immutability, higher-order functions, algebraic data types, and pattern matching. It also supports object-oriented programming via structs, enums, traits, and methods. Rust enforces memory safety (i.e., that all references point to valid memory) without a conventional garbage collector; instead, memory safety errors and data races are prevented by the "borrow checker", which tracks the object lifetime of references at compile time.
