Trait OrderKeyInit 

pub trait OrderKeyInit: OrderScheme + Sized {
    type Key: Controlled;
    type KeyError: Error + Send + Sync + 'static;

    // Required methods
    fn new(key: Self::Key) -> Self;
    fn try_from_bytes(key: Protected<Vec<u8>>) -> Result<Self, Self::KeyError>;
}

A scheme keyed from secret bytes, as PrfKeyInit keys a PRF, so an index layer can construct any scheme the same way.

Required Associated Types

type Key: Controlled

The scheme’s full-strength key, a protected array.

type KeyError: Error + Send + Sync + 'static

Why key material of a length only known at runtime was refused.

Required Methods

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

Key the scheme with a full-strength key. Cannot fail: the type carries the length.

fn try_from_bytes(key: Protected<Vec<u8>>) -> Result<Self, Self::KeyError>

Key the scheme with material whose length is only known at runtime, such as a KMS response.

Errors

KeyError if the material is unfit, a short key say. Accepting it would produce terms anyone can order.

Dyn Compatibility

This trait is not dyn compatible.

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