Rust NonZeroI16.saturating_abs用法及代碼示例

#![feature(nonzero_ops)]

let pos = NonZeroI16::new(1)?;
let neg = NonZeroI16::new(-1)?;
let min = NonZeroI16::new(i16::MIN)?;
let min_plus = NonZeroI16::new(i16::MIN + 1)?;
let max = NonZeroI16::new(i16::MAX)?;

assert_eq!(pos, pos.saturating_abs());
assert_eq!(pos, neg.saturating_abs());
assert_eq!(max, min.saturating_abs());
assert_eq!(max, min_plus.saturating_abs());
