func OnlyDisconnected ¶

func OnlyDisconnected(err error, protocol func(error) bool) bool

OnlyDisconnected requires every leaf to identify a disconnected connection. EOF and syscall failures require a net.OpError ancestor; TLS delegates can return the same errors without any socket failure. net.ErrClosed is explicit. protocol may recognize additional protocol-specific leaves. Unknown failures, classified faults and incomplete inspection remain failures. Never use this to classify queries, commands, transactions, or shutdown wait deadlines.
