Trait CheckedAbs 

pub trait CheckedAbs: Sized {
    type Output;

    // Required method
    fn checked_abs(self) -> Option<Self::Output>;
}

Computes the absolute value, returning None if it can’t be represented.

Required Associated Types

type Output

The result type (Self for the primitive impls).

Required Methods

fn checked_abs(self) -> Option<Self::Output>

Checked absolute value. Computes self.abs(), returning None if self == MIN (the result can’t be represented).

Examples

use const_num_traits::CheckedAbs;

assert_eq!(CheckedAbs::checked_abs(-5i32), Some(5));
assert_eq!(CheckedAbs::checked_abs(i32::MIN), None);

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
