Resource: Operation
This resource represents a long-running operation that is the result of a network API call.
name 
 
  string 
 
The server-assigned name, which is only unique within the same service that originally returns it. If you use the default HTTP mapping, the name 
should be a resource name ending with operations/{uniqueId} 
.
done 
 
  boolean 
 
If the value is false 
, it means the operation is still in progress. If true 
, the operation is completed, and either error 
or response 
is available.
result 
 
  Union type 
 
 error 
or a valid response 
. If done 
== false 
, neither error 
nor response 
is set. If done 
== true 
, exactly one of error 
or response 
can be set. Some services might not provide the result. result 
can be only one of the following:error 
 
  object (  Status 
 
) 
 
The error result of the operation in case of failure or cancellation.
response 
 
  object 
 
The normal, successful response of the operation. If the original method returns no data on success, such as Delete 
, the response is google.protobuf.Empty 
. If the original method is standard Get 
/ Create 
/ Update 
, the response should be the resource. For other methods, the response should have the type XxxResponse 
, where Xxx 
is the original method name. For example, if the original method name is TakeSnapshot() 
, the inferred response type is TakeSnapshotResponse 
.
An object containing fields of an arbitrary type. An additional field "@type" 
contains a URI identifying the type. Example: { "id": 1234, "@type": "types.example.com/standard/id" } 
.

|   | Starts asynchronous cancellation on a long-running operation. | 
|   | Deletes a long-running operation. | 
|   | Gets the latest state of a long-running operation. |
