PollOperationState interface

Package:

@azure/storage-blob

PollOperationState contains an opinionated list of the smallest set of properties needed to define any long running operation poller.

While the Poller class works as the local control mechanism to start triggering, wait for, and potentially cancel a long running operation, the PollOperationState documents the status of the remote long running operation.

It should be updated at least when the operation starts, when it's finished, and when it's cancelled. Though, implementations can have any other number of properties that can be updated by other reasons.

Properties

error	Will exist if the operation encountered any error.
isCancelled	True if the operation has been cancelled.
isCompleted	True if the operation has been completed.
isStarted	True if the operation has started.
result	Will exist if the operation concluded in a result of an expected type.
