Trait CheckedMul 

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

Performs checked multiplication. Maps directly to the integers checked_mul method. (i.e. u8::checked_mul) Consult the docs of the primitive methods to learn more.

Required Methods

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

performs checked mul

Example

let a = 2u8;
let b = 1u8;

assert_eq!(CheckedMul::checked_mul(a, b), a.checked_mul(b));
assert_eq!(CheckedMul::checked_mul(a, u8::MAX), a.checked_mul(u8::MAX));

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.
