Struct hakuban::object::ObjectExposeContract
source · pub struct ObjectExposeContract { /* private fields */ }
Expand description
Represents a wish, a contract to expose an object
ObjectExposeContract is a Stream, emitting ObjectStateSink objects.
ObjectStateSink will only get emitted if/when LocalExchange gets to know at least one observer (ObjectObserveContract or TagObserveContract) of the object the contract pertains to. ObjectExposeContract will not emit more than one ObjectStateSink at a time. New ObjectStateSink will get emitted only when previous one gets dropped.
The Stream will end when contract gets ObjectExposeContract::terminated.
Cloning
ObjectExposeContract can be cloned, but cloning does not create a new contract. Think of it as creating o paper copy of an on-paper contract. It’s a new sheet of paper, but not a new deal/agreement. Clones are basically references to a logical agreement.
Accordingly, terminating any of the clones (or the original), renders all of them terminated.
