Free public beta until December 4, 2026: every course is open, no card needed. After that, the first chapter of each course stays free and full access is a one-time $39 ($19 for up to 100 founding members chosen for helpful feedback). Your progress is kept. How the beta works

crate

A unit of Rust code the compiler builds at once: a program or a library.

A crate is the unit of compilation: a binary crate (with main) or a library crate, built from one root source file.

Examples

  • cargo new hello makes a binary crate rooted at src/main.rs; cargo new --lib fines makes a library crate rooted at src/lib.rs.
