Trait One

pub trait One {
    const ONE: Self;

    // Required method
    fn is_one(&self) -> bool;
}

Required Associated Constants

const ONE: Self

The one value for this type.

Required Methods

fn is_one(&self) -> bool

Whether the value 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.
