rust print i8

To print an i8 value in Rust, you can use the println! macro. Here's an example:

fn main() {
    let num: i8 = 42;
    println!("{}", num);
}

This code declares a variable num of type i8 and assigns it the value 42. The println! macro is then used to print the value of num to the console. The {} inside the println! macro is a placeholder that gets replaced with the value of num.

When you run this code, it will output 42 to the console.
