Rust Source Code
Rust files contain source code for the systems programming language that guarantees memory safety without a garbage collector. Rust uses its ownership system and borrow checker to prevent data races and null pointer errors at compile time.

Lossless
Advantages
- + Memory safety guaranteed at compile time — no GC needed
- + Performance comparable to C and C++
- + Fearless concurrency — data races are compile errors
- + Excellent tooling: Cargo, rustfmt, clippy
Disadvantages
- − Steep learning curve — ownership and lifetimes take time to master
- − Longer compilation times than Go or C
- − Smaller ecosystem than Python, Java, or JavaScript
When to Use .RS
Use Rust for systems programming, WebAssembly, game engines, embedded systems, and any software requiring memory safety without GC overhead.
Technical Details
Rust's ownership system tracks data lifetimes at compile time. Every value has a single owner, references follow borrowing rules, and the borrow checker prevents use-after-free and data races. Cargo is the build system and package manager.
History
Graydon Hoare started Rust at Mozilla in 2010. Version 1.0 was released in 2015. The Rust Foundation was established in 2021. Rust has been voted the most admired programming language in Stack Overflow surveys since 2016.
