Class Empty (3.23.0)

public sealed class Empty : IMessage<Empty>, IEquatable<Empty>, IDeepCloneable<Empty>, IBufferMessage, IMessage

A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance:

service Foo {
  rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty);
}
