}Expand description
An abstraction of the (possibly distributed) store for objects. This API only allows for the retrieval of objects, not any state changes
Required Methods§
sourcefn read_child_object(
&self,
parent: &ObjectID,
child: &ObjectID,
child_version_upper_bound: SequenceNumber
) -> SuiResult<Option<Object>>
fn read_child_object( &self, parent: &ObjectID, child: &ObjectID, child_version_upper_bound: SequenceNumber ) -> SuiResult<Option<Object>>
child must have an ObjectOwner ownership equal to owner.
sourcefn get_object_received_at_version(
&self,
owner: &ObjectID,
receiving_object_id: &ObjectID,
receive_object_at_version: SequenceNumber,
epoch_id: EpochId
) -> SuiResult<Option<Object>>
fn get_object_received_at_version( &self, owner: &ObjectID, receiving_object_id: &ObjectID, receive_object_at_version: SequenceNumber, epoch_id: EpochId ) -> SuiResult<Option<Object>>
receiving_object_id must have an AddressOwner ownership equal to owner.
get_object_received_at_version must be the exact version at which the object will be received,
and it cannot have been previously received at that version. NB: An object not existing at
that version, and not having valid access to the object will be treated exactly the same
and Ok(None) must be returned.
