Returns the validator groups and rotation info localized based on the hypothetical child of a block whose state this is invoked on. Note that now in the GroupRotationInfo should be the successor of the number of the block.

fn availability_cores<'life0, 'async_trait>( &'life0 self, at: Hash ) -> Pin<Box<dyn Future<Output = Result<Vec<CoreState<Hash, BlockNumber>>, ApiError>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait,

Yields information on all availability cores as relevant to the child block. Cores are either free or occupied. Free cores can have paras assigned to them.

fn persisted_validation_data<'life0, 'async_trait>( &'life0 self, at: Hash, para_id: Id, assumption: OccupiedCoreAssumption ) -> Pin<Box<dyn Future<Output = Result<Option<PersistedValidationData<Hash, BlockNumber>>, ApiError>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait,

Yields the persisted validation data for the given ParaId along with an assumption that should be used if the para currently occupies a core.

Returns None if either the para is not registered or the assumption is Freed and the para already occupies a core.

Returns the persisted validation data for the given ParaId along with the corresponding validation code hash. Instead of accepting assumption about the para, matches the validation data hash against an expected one and yields None if they’re not equal.
