Use this reference to work with Cargo, Rust’s package manager and build tool. It explains project manifests, dependencies, features, workspaces, build profiles, configuration, registries, publishing, and commands for building, testing, and inspecting projects.
Use when working with the cargo CLI — Rust's package manager. Covers the manifest format (Cargo.toml), dependencies, features, workspaces, build profiles, build scripts, configuration (.cargo/config.toml), registries and publishing, environment variables, the lockfile and cache, and the command reference. Triggers on: "cargo", "cargo build", "cargo check", "cargo test", "cargo run", "cargo add", "cargo update", "cargo publish", "cargo new", "cargo init", "cargo install", "cargo doc", "cargo bench", "cargo tree", "cargo metadata", "Cargo.toml", "Cargo.lock", "crate", "workspace", "feature", "profile", "build script", "build.rs", "registry", "crates.io", "CARGO_HOME", "rustc", "rustdoc", "rust-version", "edition".

Comprehensive reference for the cargo CLI (https://doc.rust-lang.org/cargo/), covering the manifest format, dependency specification, the features system and resolver, workspaces, build profiles, build scripts, configuration, registries and publishing, environment variables, the lockfile and cache layout, and the full command reference.
Cargo.toml (manifest)
→ dependency resolver (registry index + Cargo.lock)
→ fetch (registry cache / git / path / vendor)
→ build scripts (build.rs, OUT_DIR)
→ rustc / rustdoc (per profile, per target)
→ target/<profile>/ (artifacts)
→ run / test / bench / install
