Functions ¶

func MustClose ¶

func MustClose(c io.Closer)

MustClose closes Closer c and calls log.Fatal if it returns a non-nil error.

func MustWriter ¶

func MustWriter(w io.Writer) io.Writer

MustWriter returns a Writer that wraps the provided Writer, except that it calls log.Fatal instead of returning a non-nil error.
