public sealed class PreconditionFailure : IMessage<PreconditionFailure>, IEquatable<PreconditionFailure>, IDeepCloneable<PreconditionFailure>, IBufferMessage, IMessage
Describes what preconditions have failed.
For example, if an RPC failed because it required the Terms of Service to be
acknowledged, it could list the terms of service violation in the
PreconditionFailure message.
