Trait One

pub trait One {
    const ONE: Self;
}

Types equipped with a multiplicative identity (i.e., one).

Required Associated Constants

const ONE: Self

Additive identity (i.e., one).

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.
