Trait KeySizeUser

pub trait KeySizeUser {
    type KeySize: ArrayLength<u8> + 'static;

    // Provided method
    fn key_size() -> usize { ... }
}

Types which use key for initialization.

Generally it’s used indirectly via KeyInit or KeyIvInit.

Required Associated Types

type KeySize: ArrayLength<u8> + 'static

Key size in bytes.

Provided Methods

fn key_size() -> usize

Return key size in bytes.

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.
