Trait Semigroup 

pub trait Semigroup: Clone {
    // Required method
    fn mappend(&self, other: &Self) -> Self;
}

Semigroup type class

Required Methods

fn mappend(&self, other: &Self) -> Self

combine 2 of the same type

Examples

use funlib::Semigroup;
assert_eq!(4i32, 1i32.mappend(&3i32));
assert_eq!(Some(4i32), Some(1i32).mappend(&Some(3i32)));

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.
