Expand description

Message to the Approval Voting subsystem.

Variants§

§

CheckAndImportAssignment(IndirectAssignmentCert, u32, Sender<AssignmentCheckResult>)

Check if the assignment is valid and can be accepted by our view of the protocol. Should not be sent unless the block hash is known.

§

CheckAndImportApproval(IndirectSignedApprovalVote, Sender<ApprovalCheckResult>)

Check if the approval vote is valid and can be accepted by our view of the protocol.

Should not be sent unless the block hash within the indirect vote is known.

§

ApprovedAncestor(H256, u32, Sender<Option<HighestApprovedAncestorBlock>>)

Returns the highest possible ancestor hash of the provided block hash which is acceptable to vote on finality for. The BlockNumber provided is the number of the block’s ancestor which is the earliest possible vote.

It can also return the same block hash, if that is acceptable to vote upon. Return None if the input hash is unrecognized.

§

GetApprovalSignaturesForCandidate(CandidateHash, Sender<HashMap<ValidatorIndex, Signature, RandomState>>)

Retrieve all available approval signatures for a candidate from approval-voting.

This message involves a linear search for candidates on each relay chain fork and also requires calling into approval-distribution: Calls should be infrequent and bounded.
