Trait PRF 

pub trait PRF {
    type Seed;
    type Input;
    type Output;

    // Required method
    fn prf(
        &self,
        seed: &Self::Seed,
        input: &[Self::Input],
    ) -> Result<Self::Output, Error>;
}

A trait for a pseudorandom function.

Required Associated Types

type Seed

type Input

type Output

Required Methods

fn prf( &self, seed: &Self::Seed, input: &[Self::Input], ) -> Result<Self::Output, Error>

Returns the output for the given seed and input.

Dyn Compatibility

This trait is dyn compatible.

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

Implementations on Foreign Types
