Required Associated Types

type Input

Input to the commitment

type Output: Clone + Debug + PartialEq + Eq + Hash

The type of output commitment value

type Randomness: Clone + Debug + PartialEq + Eq + UniformRand

The type of the hiding/blinding factor

type Error: Error

Error type

Required Methods

fn commit<T: Borrow<Self::Input>>( input: T, r: Option<&Self::Randomness>, ) -> Result<Self::Output, Self::Error>

Commit algorithm that takes input and blinding randomness r (optional for hiding commitment schemes), outputs a commitment.

fn verify<T: Borrow<Self::Input>>( input: T, r: Option<&Self::Randomness>, comm: &Self::Output, ) -> Result<Result<(), ()>, Self::Error>

Verify algorithm that output Ok if accepted, or Err if rejected.

Dyn Compatibility

This trait is not dyn compatible.

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