Struct polkadot_node_subsystem_util :: inclusion_emulator :: Fragment Copy item path

impl Fragment

pub fn new( relay_parent: RelayChainBlockInfo, operating_constraints: Constraints, candidate: Arc<ProspectiveCandidate>, ) -> Result<Self, FragmentValidityError>

Create a new fragment.

This fails if the fragment isn’t in line with the operating constraints. That is, either its inputs or its outputs fail checks against the constraints.

This doesn’t check that the collator signature is valid or whether the PoV is small enough.

pub fn check_against_constraints( relay_parent: &RelayChainBlockInfo, operating_constraints: &Constraints, commitments: &CandidateCommitments, validation_code_hash: &ValidationCodeHash, persisted_validation_data: &PersistedValidationData, ) -> Result<ConstraintModifications, FragmentValidityError>

Check the candidate against the operating constrains and return the constraint modifications made by this candidate.

pub fn relay_parent(&self) -> &RelayChainBlockInfo

Access the relay parent information.

pub fn operating_constraints(&self) -> &Constraints

Access the operating constraints

pub fn candidate(&self) -> &ProspectiveCandidate

Access the underlying prospective candidate.

pub fn candidate_clone(&self) -> Arc<ProspectiveCandidate>

Get a cheap ref-counted copy of the underlying prospective candidate.

pub fn constraint_modifications(&self) -> &ConstraintModifications

Modifications to constraints based on the outputs of the candidate.
