Types which can be initialized from key.

Required Methods

fn new(key: &Key<Self>) -> Self

Create new value from fixed size key.

Provided Methods

fn weak_key_test(_key: &Key<Self>) -> Result<(), WeakKeyError>

Check if the key might be considered weak.

fn new_checked(key: &Key<Self>) -> Result<Self, WeakKeyError>

Create new value from fixed size key after checking it for weakness.

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

Create new value from variable size key.

fn generate_key() -> Result<Key<Self>, OsError>

Available on crate feature os_rng only.

Generate random key using the operating system’s secure RNG.

fn generate_key_with_rng<R: CryptoRng + ?Sized>(rng: &mut R) -> Key<Self>

Available on crate feature rand_core only.

Generate random key using the provided CryptoRng.

fn try_generate_key_with_rng<R: TryCryptoRng + ?Sized>( rng: &mut R, ) -> Result<Key<Self>, R::Error>

Available on crate feature rand_core only.

Generate random key using the provided TryCryptoRng.

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.
