import { DatastoreOperations } from "https://deno.land/x/google_datastore@0.0.14/mod.ts";
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
.
