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 NewBufReader(r io.Reader) io.ReadCloser
NewBufReader returns a new bufReader.
func NewBufReaderWithDrainbufAndBuffer ¶
func NewBufReaderWithDrainbufAndBuffer(r io.Reader, drainBuffer []byte, buffer *bytes.Buffer) io.ReadCloser
NewBufReaderWithDrainbufAndBuffer returns a BufReader with drainBuffer and buffer.
func NewReadCloserWrapper ¶
func NewReadCloserWrapper(r io.Reader, closer func() error) io.ReadCloser
NewReadCloserWrapper returns a new io.ReadCloser.
func NewReaderErrWrapper ¶
NewReaderErrWrapper returns a new io.Reader.
func NewWriteCloserWrapper ¶
func NewWriteCloserWrapper(r io.Writer, closer func() error) io.WriteCloser
NewWriteCloserWrapper returns a new io.WriteCloser.
func NopWriteCloser ¶
func NopWriteCloser(w io.Writer) io.WriteCloser
NopWriteCloser returns a nopWriteCloser.
Types ¶
type NopFlusher ¶
type NopFlusher struct{}
NopFlusher represents a type which flush opetatin is nop.
type OnEOFReader ¶
type OnEOFReader struct {
Rc io.ReadCloser
Fn func()
}
OnEOFReader wraps a io.ReadCloser and a function the fuction will run at the end of file or close the file.
func (*OnEOFReader) Close ¶
func (r *OnEOFReader) Close() error
Close closes the file and run the function.
type WriteCounter ¶
WriteCounter wraps 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
NewWriteCounter returns a new WriteCounter.
type WriteFlusher ¶
WriteFlusher wraps the Write and Flush operation.
func NewWriteFlusher ¶
func NewWriteFlusher(w io.Writer) *WriteFlusher
NewWriteFlusher returns a new WriteFlusher.
func (*WriteFlusher) Flushed ¶
func (wf *WriteFlusher) Flushed() bool
Flushed returns the state of flushed. If it's flushed, return true, or else it return false.
