Struct SubstateSchemaMapper 

pub struct SubstateSchemaMapper<'a, S>
where
    S: SubstateDatabase,
{ /* private fields */ }

A builder of SubstateSystemStructures. Note that the implementation below assumes that substate owned objects can not be detached. If this changes, we will have to account for objects that are removed from a substate.

Implementations

impl<'a, S> SubstateSchemaMapper<'a, S>

where S: SubstateDatabase,

pub fn new( system_reader: SystemDatabaseReader<'a, S>, ) -> SubstateSchemaMapper<'a, S>

Creates an empty builder.

pub fn add_substate_structure( &mut self, node_id: &NodeId, partition_num: &PartitionNumber, key: &SubstateKey, )

Resolves a SubstateSystemStructure of the given substate and adds it to the build.

pub fn add_substate_structures(&mut self, state_updates: &StateUpdates)

A batch add_substate_structure() counterpart, tailored for processing all substates written to the track (i.e. skipping reads).

pub fn add_for_all_individually_updated(&mut self, updates: &StateUpdates)

A batch add_substate_structure() counterpart, tailored for processing all substates that were individually updated in the given StateUpdates (i.e. ignoring substates affected as part of a batch, e.g. during a partition deletion).

pub fn done( self, ) -> IndexMap<NodeId, IndexMap<PartitionNumber, IndexMap<SubstateKey, SubstateSystemStructure>>>

Finalizes the build.
