Trait KeyInit 

pub trait KeyInit: Sized + KeySizeUser {
    // Required method
    fn new(key: &GenericArray<u8, Self::KeySize>) -> Self;

    // Provided methods
    fn new_from_slice(key: &[u8]) -> Result<Self, InvalidLength> { ... }
    fn generate_key(
        rng: impl CryptoRng + RngCore,
    ) -> GenericArray<u8, Self::KeySize> { ... }
}

Types which can be initialized from key.

Required Methods

fn new(key: &GenericArray<u8, Self::KeySize>) -> Self

Create new value from fixed size key.

Provided Methods

fn new_from_slice(key: &[u8]) -> Result<Self, InvalidLength>

Create new value from variable size key.

fn generate_key( rng: impl CryptoRng + RngCore, ) -> GenericArray<u8, Self::KeySize>

Generate random key using the provided CryptoRng.

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.
