Types

type CloseCallback

type CloseCallback func()

An CloseCallback is a callback type called when a Writer is closed

type Writer

type Writer struct {
	Writer      io.Writer
	BeforeClose CloseCallback
	AfterClose  CloseCallback
}

Writer implements io.WriteCloser and has callbacks for before and after the underlying writer is closed

func (*Writer) Close

func (w *Writer) Close() error

Close first calls OnClose, then closes the underlying writer (if the callback didn't return an error)

func (*Writer) Write

func (w *Writer) Write(buf []byte) (int, error)

Write relays the write directly to the underlying writer
