num_traits::identities

Trait ConstOne

Source
pub trait ConstOne: One {
    const ONE: Self;
}
Expand description

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

Required Associated Constants§

Source

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", so this trait is not object safe.
