This can be modified with the RUSTUP_HOME environment variable.
The Cargo home directory located at:

The cargo, rustc, rustup and other commands will be added to
Cargo's bin directory, located at:

Rust is installed now. Great!
To get started you may need to restart your current shell.
This would reload your PATH environment variable to include
Cargo's bin directory ($HOME/.cargo/bin).
To configure your current shell, run:
source $HOME/.cargo/env
rajdeepsingh@officialrajdeepsingh:/$

At the End of the step, you just source $HOME/.cargo/env and paste the following command into the terminal. This command help to set up your current shell in your machine. So you can run rust in your current terminal or shell without restarting your machine.
