exit program rust

To exit a Rust program, you can use the std::process::exit function. This function immediately terminates the current process and returns the specified exit code.

Here is an example of how you can use std::process::exit in Rust:

use std::process;

fn main() {
    // Perform some operations

    // Exit the program with exit code 0
    process::exit(0);
}

In the code snippet above, the main function performs some operations, and then the program exits using process::exit(0). The exit code 0 indicates a successful termination of the program. You can choose a different exit code as needed.

Keep in mind that when you call std::process::exit, the program terminates immediately without executing any further code, including cleanup code or destructors. So, use it carefully and make sure you have handled any necessary cleanup before calling exit.
