type Output

Required Methods

fn hash( input: <<S as StandardCryptographicSuite>::Transformation as TransformationAlgorithm<S>>::Output, proof_configuration: ProofConfigurationRef<'_, S>, verification_method: &<S as StandardCryptographicSuite>::VerificationMethod, ) -> Result<Self::Output, HashingError>

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.
