How to uninstall Rust that was installed via rustup?

1. Open the terminal: First, open the command line terminal. On Windows, use PowerShell or Command Prompt; on macOS or Linux, use Terminal.

2. Run the uninstall command: In the terminal, enter the following command to uninstall Rust:

bash
rustup self uninstall

This command initiates an uninstaller that prompts you to confirm.

1. Confirm the uninstallation: When prompted to confirm the uninstallation, type 'y' and press Enter. After this, rustup and all its installed components, such as the Rust compiler (rustc) and Rust package manager (cargo), will be removed from your system.

2. Check environment variables: After uninstallation, it is recommended to verify the environment variables to ensure that Rust-related paths have been removed. On most systems, this step may not be necessary because rustup typically handles the relevant environment settings during uninstallation.

3. Restart the terminal: After uninstallation, close the current terminal window and open a new one to ensure that all environment variable updates are effective.

Here are the complete steps to uninstall Rust via rustup. If you need to reinstall Rust in the future, simply use the rustup installer again.
