Trait Monoid 

pub trait Monoid: Semigroup {
    // Required method
    fn zero() -> Self;
}

A semigroup with an explicit zero element.

Required Methods

fn zero() -> Self

A zero element under the semigroup addition operator.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
