Trait DefaultConst 

pub trait DefaultConst: Sized {
    const DEFAULT: Self;
}

A const version of Default.

Required Associated Constants

const DEFAULT: Self

The default value for this type. Prefer accessing this by calling value_of on DefaultOf<Self>.

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.
