IOData Enumeration Reference
IOData
public enum IODataextension IOData: Equatableextension IOData: CustomStringConvertibleIOData unifies standard SwiftNIO types that are raw bytes of data; currently ByteBuffer and FileRegion.
Many ChannelHandlers receive or emit bytes and in most cases this can be either a ByteBuffer or a FileRegion
from disk. To still form a well-typed ChannelPipeline such handlers should receive and emit value of type IOData.
