Package io.atomix.copycat.error Description

Provides error constants and exceptions associated with the Raft consensus protocol.

Copycat protocol errors are designed to be transported across networks in the most efficient manner possible. Each protocol exception is associated with a 1-byte identifier. Rather than serializing complete Exception objects, the protocol exception is sent using only its identifier and the exception is recreated by the receiving side of a connection.
