    // Provided methods
    fn derive(
        &self,
        params: Params<'_, '_, '_>,

Kbkdf is a trait representing a mode of KBKDF. It takes multiple arguments:

• Prf - the Pseudorandom Function to derive keys from
• K - the expected output length of the newly derived key
• R - An integer (1 <= r <= 32) that indicates the length of the binary encoding of the counter i as an integer in the interval [1, 2r − 1].

Provided Associated Constants

const FEEDBACK_KI: bool = false

Whether the KI should be reinjected every round.

const DOUBLE_PIPELINE: bool = false

Provided Methods

fn derive( &self, params: Params<'_, '_, '_>, ) -> Result<Array<u8, K::KeySize>, Error>

Derives key from kin and other parameters.

fn input_iv(&self, _ki: &mut Option<Array<u8, Prf::OutputSize>>)

Input the IV in the PRF

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.
