Die Rust-Toolchain erkunden

Installing Rust gave you a whole toolchain, not one program. Knowing each tool keeps your workflow smooth.

rustup is your Rust manager: it installs components, updates to the latest release, and switches between stable, beta, and nightly.

Keep Rust current with rustup update. It pulls the newest stable release and refreshes all installed components.

rustc is the compiler at the core of it all — it turns your .rs files into runnable programs. Handy for quick, single-file builds.

Here's rustc in action. Compile with rustc main.rs, then run ./main (or main.exe on Windows).

cargo is Rust's build system and package manager — the tool you'll use most. It creates projects, builds code, runs tests, and manages dependencies.

Start a project with cargo new my_project. It scaffolds a directory with a standard layout and a Cargo.toml manifest.

In a Cargo project, cargo build compiles and cargo run compiles then executes — Cargo drives rustc for you.

Every Cargo project has a Cargo.toml manifest. [package] holds name and version; [dependencies] lists the crates you pull in.

Let's test your understanding of the Rust toolchain components.

You've met the core toolchain: rustup manages installs, rustc compiles, and cargo orchestrates projects, deps, and builds. They work as a team.
