Functions ¶
func FprintfIfNotEmpty ¶
FprintfIfNotEmpty prints the string value if it's not empty
func MultiReadSeeker ¶
func MultiReadSeeker(readers ...io.ReadSeeker) 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 NewReadCloserWrapper ¶
func NewReadCloserWrapper(r io.Reader, closer func() error) io.ReadCloser
func NewWriteCloserWrapper ¶
func NewWriteCloserWrapper(r io.Writer, closer func() error) io.WriteCloser
func NopWriteCloser ¶
func NopWriteCloser(w io.Writer) io.WriteCloser
Types ¶
type OnEOFReader ¶
type OnEOFReader struct { Rc io.ReadCloser Fn func() }
func (*OnEOFReader) Close ¶
func (r *OnEOFReader) Close() error
type WriteCounter ¶
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
type WriteFlusher ¶
func NewWriteFlusher ¶
func NewWriteFlusher(w io.Writer) *WriteFlusher
func (*WriteFlusher) Flushed ¶
func (wf *WriteFlusher) Flushed() bool
