Functions

func FuncCloser

func FuncCloser(r io.Reader, closer func() error) io.ReadCloser

FuncCloser turns an io.Reader into an io.ReadCloser by calling a supplied function on Close.

func NewTracedConnection

func NewTracedConnection(conn net.Conn) net.Conn

NewTracedConnection wraps an existing connection to trace calls to methods on it.

Types

type LoggedConnection

type LoggedConnection struct {
	net.Conn
	// contains filtered or unexported fields
}

LoggedConnection is a net.Conn helper which logs all call activity. It is useful for debugging packages with opaque connection handling paths, as poller_exporter leans heavily on incremental construction of net.Conn sessions.
