Rust
Rust is a systems programming language focused on memory safety, performance comparable to C and C++, and "fearless concurrency," enforced at compile time through an ownership and borrowing model rather than a garbage collector.
Definition
Rust is a systems programming language focused on memory safety, performance comparable to C and C++, and "fearless concurrency," enforced at compile time through an ownership and borrowing model rather than a garbage collector.
Overview
Rust originated at Mozilla, created by Graydon Hoare, with its first stable release in 2015. The language grew out of a desire to write safer low-level, systems-level code — such as browser engines — without sacrificing the performance that C and C++ provide. Rust's ownership system tracks, at compile time, exactly which part of the code owns a given piece of memory, and enforces borrowing rules for references, so memory is freed automatically once it goes out of scope. This eliminates entire classes of bugs — use-after-free, data races, null pointer dereferences — without needing a garbage collector; the compiler's borrow checker enforces these rules, trading a steeper learning curve for strong compile-time safety guarantees. Rust is regularly voted one of the most-loved languages in developer surveys, and it compares favorably to languages like Python, the JavaScript runtime behind Node.js, and Go (Golang) specifically for performance-critical or safety-critical work. It's used to build parts of browser engines, the Deno and Bun JavaScript runtimes, database engines, and increasingly parts of the Linux kernel, along with a growing footprint compiling to WebAssembly for the browser.
Key Features
- Ownership and borrowing model that guarantees memory safety at compile time
- No garbage collector, giving predictable, C/C++-level performance
- Fearless concurrency — the compiler prevents data races before code runs
- Powerful pattern matching, traits, and a strong, expressive type system
- Cargo package manager and build tool with a large crates.io ecosystem
- First-class support for compiling to WebAssembly
Use Cases
History
Rust is a systems programming language focused on performance, memory safety, and safe concurrency, achieving memory safety without a garbage collector through its ownership and borrowing model. It began around 2006 as a personal side project of Graydon Hoare, then a Mozilla employee, and became a Mozilla-sponsored research project that was announced publicly in 2010 — one early proving ground was the experimental Servo browser engine. After years of development, the first stable release, Rust 1.0, shipped on May 15, 2015. Rust developed an independent governance structure and, since February 2021, has been stewarded by the nonprofit Rust Foundation. It became renowned for combining low-level control with strong safety guarantees.
