Trait One

pub trait One {
    // Required methods
    fn one() -> Self;
    fn is_one(x: &Self) -> Choice;
}

Type that has “one” value (multiplicative identity)

Required Methods

fn one() -> Self

Constructs one value of Self

fn is_one(x: &Self) -> Choice

Checks (in constant-time) if x is 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.
