public sealed class AuthenticationRule : IMessage<AuthenticationRule>, IEquatable<AuthenticationRule>, IDeepCloneable<AuthenticationRule>, IBufferMessage, IMessage
Authentication rules for the service.
By default, if a method has any authentication requirements, every request
must include a valid credential matching one of the requirements.
It's an error to include more than one kind of credential in a single
request.
If a method doesn't have any auth requirements, request credentials will be
ignored.
