Other cases

case wrongProduction(actual: OutputType, expected: OutputType)
The errorCode will be wrongProduction when the expected output didn’t match the actual output.
case underProduction(OutputType)
The errorCode will be set to underProduction when a decoder didn’t yield output when output was expected. The expected output is delivered as the associated value.
case leftOversOnDeconstructingChannel(inbound: [NIOAny], outbound: [NIOAny], pendingOutbound: [NIOAny])
The errorCode will be set to leftOversOnDeconstructionChannel if there were left-over items in the Channel on deconstruction. This usually means that your ByteToMessageDecoder did not process certain items.
