How do I get an absolute value in Rust?

fn main() {
    let mut number: i32 = -8;
    number = number.abs();
    println!("{}", number);
}

Remember that you must specify the datatype explicitly.

The answer mentioning std::num::abs doesn't work anymore.

Instead, use:

i32::abs(n)

Nowadays, abs is a method on most number types.

let value = -42i32;
let x = value.abs();
