Trait ConstOne 

pub trait ConstOne: Sized {
    const ONE: Self;
}

Defines an associated constant representing the multiplicative identity element for Self.

A pure constant-carrier, decoupled from One (and hence Mul) for the same reason as ConstZero: a type can supply the compile-time 1 that PrimBits needs without implementing multiplication. Numeric types still implement both.

Required Associated Constants

const ONE: Self

The multiplicative identity element of Self, 1.

Dyn Compatibility

This trait is not dyn compatible.

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