# Rust: Not AI-friendly

> In rust-lang/rust, cargo, clippy and other adopting repositories, LLMs may be used privately to answer questions, analyse, review and suggest, but not to create. LLM-written comments, issue bodies, PR descriptions and docs are banned; trivial changes, machine translation and verified LLM-found bugs need disclosure, and LLM-created code is only allowed in a pre-arranged, disclosed experiment.

- What it is: A systems programming language focused on safety, speed and concurrency. (Programming language)
- Homepage: https://www.rust-lang.org/
- Repository: https://github.com/rust-lang/rust
- Overall stance: Not AI-friendly (Unfriendly). AI-generated contributions are not accepted; at most minor help such as autocomplete or grammar fixes.
