Exported Values


	 func DataErrReader(r io.Reader) io.Reader
		DataErrReader changes the way errors are handled by a Reader. Normally, a
		Reader returns an error (typically EOF) from the first Read call after the
		last piece of data is read. DataErrReader wraps a Reader and changes its
		behavior so the final error is returned along with the final data, instead
		of in the first call after the final data.



	 func HalfReader(r io.Reader) io.Reader
		HalfReader returns a Reader that implements Read
		by reading half as many requested bytes from r.


	 func NewReadLogger(prefix string, r io.Reader) io.Reader
		NewReadLogger returns a reader that behaves like r except
		that it logs (using log.Printf) each read to standard error,
		printing the prefix and the hexadecimal data read.


	 func NewWriteLogger(prefix string, w io.Writer) io.Writer
		NewWriteLogger returns a writer that behaves like w except
		that it logs (using log.Printf) each write to standard error,
		printing the prefix and the hexadecimal data written.


	 func OneByteReader(r io.Reader) io.Reader
		OneByteReader returns a Reader that implements
		each non-empty Read by reading one byte from r.


	 func TimeoutReader(r io.Reader) io.Reader
		TimeoutReader returns ErrTimeout on the second read
		with no data. Subsequent calls to read succeed.


	 func TruncateWriter(w io.Writer, n int64) io.Writer
		TruncateWriter returns a Writer that writes to w
		but stops silently after n bytes.
