Trait KeyAeadMeta 

pub trait KeyAeadMeta {
    type NonceSize: ArrayLength<u8>;
    type TagSize: ArrayLength<u8>;

    // Provided method
    fn random_nonce() -> GenericArray<u8, Self::NonceSize> { ... }
}

For concrete key types with fixed nonce and tag sizes

Required Associated Types

type NonceSize: ArrayLength<u8>

The size of the AEAD nonce

type TagSize: ArrayLength<u8>

The size of the AEAD tag

Provided Methods

fn random_nonce() -> GenericArray<u8, Self::NonceSize>

Available on crate feature getrandom only.

Generate a new random nonce

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
