Expand description

Parameters for CollationGenerationMessage::SubmitCollation.

Fields§

§relay_parent: Hash

The relay-parent the collation is built against.

§collation: Collation

The collation itself (PoV and commitments)

§validation_code_hash: ValidationCodeHash

The hash of the validation code the collation was created against.

§result_sender: Option<Sender<CollationSecondedSignal>>

An optional result sender that should be informed about a successfully seconded collation.

There is no guarantee that this sender is informed ever about any result, it is completely okay to just drop it. However, if it is called, it should be called with the signed statement of a parachain validator seconding the collation.

§core_index: CoreIndex

The core index on which the resulting candidate should be backed

§scheduling_parent: Option<Hash>

The scheduling parent for V3 candidate descriptors. If set, the candidate descriptor will use this as the scheduling parent (creating a V3 descriptor). If None, relay_parent is used (V2 descriptor).

WARNING: Should only be set if the CandidateReceiptV3 node feature is set.

§session_index: SessionIndex

The session index of the relay parent. Goes into the candidate descriptor. Must be provided by the caller because the relay parent’s state may be pruned.

§validation_data: PersistedValidationData

The persisted validation data for this collation. The parent_head field must be set to the correct parent head-data for the parablock being submitted.
