public interface IExtendableMessage<T> : IMessage<T>, IMessage, IEquatable<T>, IDeepCloneable<T> where T : IExtendableMessage<T>
Generic interface for a Protocol Buffers message containing one or more extensions, where the type parameter is expected to be the same type as the implementation class.
This interface is experiemental and is subject to change.
