RoundTrip defines the round tripper for basic auth transport.

type ErrorTransport

type ErrorTransport struct {
	Transport http.RoundTripper
}

ErrorTransport defines the data structure for returning errors from the round tripper.

func (*ErrorTransport) RoundTrip

func (t *ErrorTransport) RoundTrip(request *http.Request) (*http.Response, error)

RoundTrip defines the round tripper for the error transport.

type LogfCallback

type LogfCallback func(format string, args ...interface{})
