Trait num::CheckedMul
[−]
[src]
pub trait CheckedMul: Mul<Self, Output = Self> { 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.
