A trait for producing and checking assignments.

Approval voting subsystem implements a a real implemention for it and tests use a mock implementation.

Required Methods

fn compute_assignments( &self, keystore: &LocalKeystore, relay_vrf_story: RelayVRFStory, config: &Config, leaving_cores: Vec<(CandidateHash, CoreIndex, GroupIndex)>, enable_v2_assignments: bool, ) -> HashMap<CoreIndex, OurAssignment>

Compute the assignments for the given relay VRF story.

fn check_assignment_cert( &self, claimed_core_bitfield: CoreBitfield, validator_index: ValidatorIndex, config: &Config, relay_vrf_story: RelayVRFStory, assignment: &AssignmentCertV2, backing_groups: Vec<GroupIndex>, ) -> Result<DelayTranche, InvalidAssignment>

Check the assignment cert for the given relay VRF story and returns the delay tranche.
