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

Available on crate feature rand_core only.

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", so this trait is not object safe.

Implementations on Foreign Types

impl<P> KeyInit for DecapsulationKey<P>

where P: KemParams,

Initialize DecapsulationKey from a 64-byte uniformly random Seed value.

fn new( seed: &Array<u8, UInt<UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>, B0>>, ) -> DecapsulationKey<P>

impl<T, S> KeyInit for XofFixedWrapper<T, S>

where T: ExtendableOutput + KeyInit, S: ArraySize,

fn new( key: &Array<u8, <XofFixedWrapper<T, S> as KeySizeUser>::KeySize>, ) -> XofFixedWrapper<T, S>
