Trait r3::utils::Init

pub trait Init {
    const INIT: Self;
}

Trait for types having a constant default value. This is essentially a constant version of Default.

This trait is subject to the application-side API stability guarantee.

Required Associated Constants

const INIT: Self

The default value.
