Trait CheckedRem 

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

Complete re-export of num-traits for SciRS2 ecosystem Performs an integral remainder that returns None instead of panicking on division by zero and instead of wrapping around on underflow and overflow.

Required Methods

fn checked_rem(&self, v: &Self) -> Option<Self>

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

Examples

use 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", so this trait is not object safe.
