New versions of Rust are released periodically. To update your installed Rust to the latest version, you don't need to uninstall the old version; you can use the rustup tool to perform the upgrade.

Check Rust Version

You can use the rustc -V command to check the currently installed Rust version:

rustc -V
rustc 1.88.0 (6b00bc388 2025-06-23)

Update Rust

You can use the rustup update command to update Rust. This command will update all installed toolchains (stable, beta, nightly).

rustup update

To update only the stable version, you can run:

rustup update stable
