- Core/runtime: Rust

A systems programming language focused on memory safety, concurrency, and performance without a garbage collector.

Rust delivers high-performance execution by eliminating common memory errors through its strict ownership model and borrow checker. It powers critical infrastructure like the Firecracker VMM, Linux kernel modules, and the Discord backend (handling 11 million concurrent users). By providing zero-cost abstractions and a robust package manager in Cargo, Rust enables developers to build reliable software that matches C++ speeds while preventing data races and null pointer dereferences.
