Required Associated Types

type Error: Error + Send + Sync + 'static

Required Methods

fn next_share( &self, pseudonym: &S::Pseudonym, msg: &impl AsRef<[u8]>, ) -> Result<Option<GeneratedShare<S>>, Self::Error>

Generate the next crate::PartialSsaShare for the given pseudonym and message msg.

IMPORTANT: Each msg MUST be unique for a given pseudonym.

Returns None if all polynomials for the given pseudonym have been used up. This signals that a new SSA must be committed.

fn new_ssa_commitment( &self, pseudonym: &S::Pseudonym, ssa_index: SsaIndex, ) -> Result<SsaCommitment<S>, Self::Error>

Generates a new SSA commitment from the sender side, for the given pseudonym.

Returns the new random SSA-commitment and the corresponding SSA share verifier.

Dyn Compatibility

This trait is not dyn compatible.

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