func FprintfIfNotEmpty

func FprintfIfNotEmpty(w io.Writer, format, value string) (int, error)

FprintfIfNotEmpty prints the string value if it's not empty

func HashData

func HashData(src io.Reader) (string, error)

func MultiReadSeeker

func MultiReadSeeker(readers io.ReadSeeker

MultiReadSeeker returns a ReadSeeker that's the logical concatenation of the provided input readseekers. After calling this method the initial position is set to the beginning of the first ReadSeeker. At the end of a ReadSeeker, Read always advances to the beginning of the next ReadSeeker and returns EOF at the end of the last ReadSeeker. Seek can be used over the sum of lengths of all readseekers.

When a MultiReadSeeker is used, no Read and Seek operations should be made on its ReadSeeker components. Also, users should make no assumption on the state of individual readseekers while the MultiReadSeeker is used.

func NewBufReader

func NewBufReader(r io.Reader) *bufReader

func NewBufReaderWithDrainbufAndBuffer

func NewBufReaderWithDrainbufAndBuffer(r io.Reader, drainBuffer []byte, buffer *bytes.Buffer) *bufReader

func NewReadCloserWrapper

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

func NewReaderErrWrapper

func NewReaderErrWrapper(r io.Reader, closer func()) io.Reader

func NewWriteCloserWrapper

func NewWriteCloserWrapper(r io.Writer, closer func() error) io.WriteCloser

func NopWriteCloser

func NopWriteCloser(w io.Writer) io.WriteCloser


type NopFlusher

type NopFlusher struct{}

func (*NopFlusher) Flush

func (f *NopFlusher) Flush()

type NopWriter

type NopWriter struct{}

func (*NopWriter) Write

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

type OnEOFReader

type OnEOFReader struct {
	Rc io.ReadCloser
	Fn func()

func (*OnEOFReader) Close

func (r *OnEOFReader) Close() error

func (*OnEOFReader) Read

func (r *OnEOFReader) Read(p []byte) (n int, err error)

type WriteCounter

type WriteCounter struct {
	Count  int64
	Writer io.Writer

Wrap a concrete io.Writer and hold a count of the number of bytes written to the writer during a "session". This can be convenient when write return is masked (e.g., json.Encoder.Encode())

func NewWriteCounter

func NewWriteCounter(w io.Writer) *WriteCounter

func (*WriteCounter) Write

func (wc *WriteCounter) Write(p []byte) (count int, err error)

type WriteFlusher

type WriteFlusher struct {
	// contains filtered or unexported fields

func NewWriteFlusher

func NewWriteFlusher(w io.Writer) *WriteFlusher

func (*WriteFlusher) Flush

func (wf *WriteFlusher) Flush()

Flush the stream immediately.

func (*WriteFlusher) Flushed

func (wf *WriteFlusher) Flushed() bool

func (*WriteFlusher) Write

func (wf *WriteFlusher) Write(b []byte) (n int, err error)
