Trait argmin::prelude::CheckedRem[][src]

pub trait CheckedRem: Rem<Self, Output = Self> {
    pub fn checked_rem(&self, v: &Self) -> Option<Self>;

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

pub fn checked_rem(&self, v: &Self) -> Option<Self>[src]

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