Trait 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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
