Trait KeyInit 

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

    // Provided methods
    fn new_from_slice(key: &[u8]) -> Result<Self, InvalidLength> { ... }
    fn generate_key<R>(rng: &mut R) -> Array<u8, Self::KeySize>
       where R: CryptoRng { ... }
}

Types which can be initialized from a key.

Required Methods

fn new(key: &Array<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.

Errors

Returns [InvalidLength] in the event the length of the provided slice is not equal to <Self as KeySizeUser>::KeySize::USIZE.

fn generate_key<R>(rng: &mut R) -> Array<u8, Self::KeySize>

where R: CryptoRng,

👎Deprecated since 0.2.0:

use the Generate trait impl on Key instead

DEPRECATED: generate random key using the provided [CryptoRng].

Instead, you can now use the [Generate] trait directly with the [Key] type:

let key = Key::generate_from_rng(rng);

Dyn Compatibility

This trait is not dyn compatible.

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