Trait argmin::prelude::ops::checked::CheckedSub[−][src]

pub trait CheckedSub: Sub<Self, Output = Self> {
    fn checked_sub(&self, v: &Self) -> Option<Self>;
}
Expand description

Performs subtraction that returns None instead of wrapping around on underflow.

Required methods

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

Subtracts two numbers, checking for underflow. If underflow happens, None is returned.
