Methods
cancelOperation(request, optionsopt, callbackopt) → {Promise}
Starts asynchronous cancellation on a long-running operation. The server
makes a best effort to cancel the operation, but success is not
guaranteed. If the server doesn't support this method, it returns
google.rpc.Code.UNIMPLEMENTED
. Clients can use
Operations.GetOperation or
other methods to check whether the cancellation succeeded or whether the
operation completed despite cancellation. On successful cancellation,
the operation is not deleted; instead, it becomes an operation with
an Operation.error value with a google.rpc.Status.code of
1, corresponding to Code.CANCELLED
.
