crates.io is the official package (crate) repository of the Rust ecosystem. It is the registry Cargo queries by default when resolving the dependencies in Cargo.toml; packages are uploaded with cargo publish and pulled in with cargo add. A version, once published, cannot be deleted and can only be hidden with yank, which guarantees reproducible dependencies, and documentation for each crate is generated automatically on docs.rs.
