Update Rust to the latest version by running the rustup update command in your terminal.
Run rustup update to download and install the latest stable Rust version. This command updates the rustup tool itself and then fetches the newest compiler toolchain.
rustup update
If you need a specific version or the nightly toolchain, use rustup toolchain install <version> followed by rustup default <version>.
Rust uses a tool called rustup to manage its versions, similar to how a phone updates its operating system. Running the update command ensures you have the latest features and security fixes without breaking your current projects. It automatically handles downloading and switching to the new version for you.
