Trait runtime::FixedPointTraits::CheckedMul

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

Performs multiplication that returns None instead of wrapping around on underflow or overflow.

Required Methods

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

Multiplies two numbers, checking for underflow or overflow. If underflow or overflow happens, None is returned.
