[−]Trait astral::thirdparty::num_traits::ops::checked::CheckedRem
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);
