Types ¶
type ReadSeekBuffer ¶
type ReadSeekBuffer struct {
// contains filtered or unexported fields
}
A Buffer is a fix-sized buffer of bytes with Read and Write methods.
func NewReadSeekBuffer ¶
func NewReadSeekBuffer(buf []byte) *ReadSeekBuffer
NewReadSeekBuffer creates and initializes a new NewReadSeekBuffer using buf as its initial contents. It is intended to prepare a NewReadSeekBuffer to read existing data.
func (*ReadSeekBuffer) Read ¶
func (b *ReadSeekBuffer) Read(p []byte) (n int, err error)
Read reads the next len(p) bytes from the buffer or until the buffer is drained. The return value n is the number of bytes read. If the buffer has no data to return, err is io.EOF (unless len(p) is zero); otherwise it is nil.
func (*ReadSeekBuffer) Seek ¶
func (b *ReadSeekBuffer) Seek(offset int64, whence int) (ret int64, err error)
Seek sets the offset for the next Read on buffer to offset, interpreted according to whence: 0 means relative to the origin of the file, 1 means relative to the current offset, and 2 means relative to the end. It returns the new offset and an error, if any.
