// In client libraries, each proto RPC corresponds to one or more methods
// which the end user is able to call, and calls the underlying RPC.
// Normally, this method receives a single argument (a struct or instance
// corresponding to the RPC request object). Defining this field will
// add one or more overloads providing flattened or simpler method signatures
// in some languages.
//
// The fields on the method signature are provided as a comma-separated
// string.
//
// For example, the proto RPC and annotation:
//
// rpc CreateSubscription(CreateSubscriptionRequest)
// returns (Subscription) {
// option (google.api.method_signature) = "name,topic";
// }
//
// Would add the following Java overload (in addition to the method accepting
// the request object):
//
// public final Subscription createSubscription(String name, String topic)
//
// The following backwards-compatibility guidelines apply:
//
// * Adding this annotation to an unannotated method is backwards
// compatible.
// * Adding this annotation to a method which already has existing
// method signature annotations is backwards compatible if and only if
// the new method signature annotation is last in the sequence.
// * Modifying or removing an existing method signature annotation is
// a breaking change.
// * Re-ordering existing method signature annotations is a breaking
// change.
