Availability Distribution Message.

Variants§

§

FetchPoV

Instruct availability distribution to fetch a remote PoV.

NOTE: The result of this fetch is not yet locally validated and could be bogus.

Fields

§relay_parent: Hash

The relay parent giving the necessary context.

§from_validator: ValidatorIndex

Validator to fetch the PoV from.

§para_id: Id

The id of the parachain that produced this PoV. This field is only used to provide more context when logging errors from the AvailabilityDistribution subsystem.

§candidate_hash: CandidateHash

Candidate hash to fetch the PoV for.

§pov_hash: Hash

Expected hash of the PoV, a PoV not matching this hash will be rejected.

§tx: Sender<PoV>

Sender for getting back the result of this fetch.

The sender will be canceled if the fetching failed for some reason.
