Trait Key 

pub trait Key {
    const LEN: usize;
}

Key trait.

The only usage of this trait is to indicate the key’s bytes length.

Required Associated Constants

const LEN: usize

Key’s bytes length.

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.

Implementors
