Required Methods§

source

fn lamport_version(&self) -> SequenceNumber

The version assigned to all output objects (apart from packages).

source

fn old_object_metadata(&self) -> Vec<(ObjectRef, Owner)>

Metadata of objects prior to modification. This includes any object that exists in the store prior to this transaction and is modified in this transaction. It includes objects that are mutated, wrapped and deleted.

source

fn input_shared_objects(&self) -> Vec<InputSharedObject>

Returns the list of sequenced shared objects used in the input. This is needed in effects because in transaction we only have object ID for shared objects. Their version and digest can only be figured out after sequencing. Also provides the use kind to indicate whether the object was mutated or read-only. It does not include per epoch config objects since they do not require sequencing. TODO: Rename this function to indicate sequencing requirement.
