  "textContent": "**Rust** is a systems programming language focused on memory safety without a garbage collector, achieved through a compile-time ownership model. It produces native binaries with C-like performance and zero-cost abstractions, while preventing entire classes of bugs (use-after-free, data races) at the type level.\n\n## Core ideas\n\n  * **Ownership and borrowing.** Each value has one owner; references are tracked by the compiler to prevent aliasing bugs.\n  * **No garbage collector.** Memory is reclaimed deterministically when values go out of scope (Drop trait).\n  * **Traits and generics.** Zero-cost abstractions via monomorphisation; expressive type system.\n  * **Fearless concurrency.** The type system prevents data races; libraries (Tokio, Rayon) provide high-level concurrency.\n  * **Cargo.** First-class build tool, dependency manager, test runner, and documentation generator.\n\n\n\n## Where Rust is used\n\n  * Systems and infra: Firefox internals, Linux kernel modules, parts of Cloudflare, AWS Firecracker\n  * Web back-ends: Actix Web, Axum, Rocket, Loco\n  * Data engines: TiKV, ScyllaDB rewrites, Pingora, Vector, Materialize, Datafusion\n  * Tooling: ripgrep, fd, bat, deno, rustdoc, the new TypeScript compiler being written in Rust\n\n\n\n🔗\n\n**Related Terms**\nGo, Microservices, gRPC.",
