Trait CheckedRem 

pub trait CheckedRem: Sized + Rem<Self> {
    // Required method
    fn checked_rem(self, v: Self) -> Option<<Self as Rem<Self>>::Output>;
}

Performs integral remainder, returning None on division by zero or if overflow occurred.

Required Methods

fn checked_rem(self, v: Self) -> Option<<Self as Rem<Self>>::Output>

Finds the remainder of dividing two numbers, checking for overflow and division by zero. If any of that happens, None is returned.

Examples

use const_num_traits::CheckedRem;
use std::i32::MIN;

assert_eq!(CheckedRem::checked_rem(10, 7), Some(3));
assert_eq!(CheckedRem::checked_rem(10, -7), Some(3));
assert_eq!(CheckedRem::checked_rem(-10, 7), Some(-3));
assert_eq!(CheckedRem::checked_rem(-10, -7), Some(-3));

assert_eq!(CheckedRem::checked_rem(10, 0), None);

assert_eq!(CheckedRem::checked_rem(MIN, 1), Some(0));
assert_eq!(CheckedRem::checked_rem(MIN, -1), None);

Dyn Compatibility

This trait is not dyn compatible.

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