Rust NonZeroI64.wrapping_abs用法及代码示例

#![feature(nonzero_ops)]

let pos = NonZeroI64::new(1)?;
let neg = NonZeroI64::new(-1)?;
let min = NonZeroI64::new(i64::MIN)?;
let max = NonZeroI64::new(i64::MAX)?;

assert_eq!(pos, pos.wrapping_abs());
assert_eq!(pos, neg.wrapping_abs());
assert_eq!(min, min.wrapping_abs());
