About Rust

Rust is a systems programming language focused on safety, speed, and concurrency, originally developed by Mozilla and first released in 2015. Rust's defining innovation is its ownership system with borrow checker — a compile-time memory management model that guarantees memory safety without a garbage collector. This eliminates entire classes of bugs: buffer overflows, use-after-free, null pointer dereferences, and data races are impossible in safe Rust. Rust consistently tops Stack Overflow's 'most loved language' survey every year since 2016, reflecting deep satisfaction among its users despite its steep learning curve. Performance is comparable to C and C++, making Rust viable for operating systems, game engines, browser engines, and embedded systems. Mozilla rewrote parts of Firefox in Rust; Amazon uses Rust in AWS (Firecracker microVM, S3); Microsoft is rewriting Windows components in Rust; the Linux kernel accepted Rust as a second supported language in 2022. Rust's WebAssembly support is best-in-class, enabling near-native browser performance. The Cargo package manager and crates.io ecosystem have 140,000+ packages. Rust's main drawback is its learning curve — the borrow checker requires a fundamentally different mental model for memory management, typically taking weeks to months to internalize. Compile times are also longer than Go. For systems-level and performance-critical code, Rust is increasingly the language of choice over C++.
