Defines a proto annotation that describes a string field that refers to an API resource.

Attributes

• childType (type: String.t, default: nil) - The resource type of a child collection that the annotated field references. This is useful for annotating the parent field that doesn't have a fixed resource type. Example: message ListLogEntriesRequest { string parent = 1 [(google.api.resource_reference) = { child_type: "logging.googleapis.com/LogEntry" }; }
• type (type: String.t, default: nil) - The resource type that the annotated field references. Example: message Subscription { string topic = 2 [(google.api.resource_reference) = { type: "pubsub.googleapis.com/Topic" }]; } Occasionally, a field may reference an arbitrary resource. In this case, APIs use the special value in their resource reference. Example: message GetIamPolicyRequest { string resource = 2 [(google.api.resource_reference) = { type: "" }]; }
