8 commands

Pro Tips

Use 'rustup default stable' and 'rustup override set nightly' per-project for different toolchains.

Add cross-compilation targets: 'rustup target add wasm32-unknown-unknown' for WebAssembly.

Update everything: 'rustup update' updates all installed toolchains and components.

Common Mistakes

Nightly features can break between releases. Pin a specific nightly date in rust-toolchain.toml for stability.

Some components aren't available on all nightly builds. Use 'rustup component add --toolchain nightly' and check availability.
