pub trait OverflowingSub: Sized + Sub<Output = Self> {
    // Required method
    fn overflowing_sub(&self, v: &Self) -> (Self, bool);
}
Expand description

Performs substraction with a flag for overflow.

Required Methods§

source

fn overflowing_sub(&self, v: &Self) -> (Self, bool)

Returns a tuple of the difference along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would have occurred then the wrapped value is returned.

Object Safety§

This trait is not object safe.
