Method takeSmallBuffer

buffer.go:126–131

takeSmallBuffer is shortcut which can be used if length is known to be smaller than defaultBufSize. Only one buffer (total) can be used at a time.

(length int)

// known to be smaller than defaultBufSize.
// Only one buffer (total) can be used at a time.
func (b *buffer) takeSmallBuffer(length int) ([]byte, error) {
	if b.busy() {
		return nil, ErrBusyBuffer
	}
	return b.cachedBuf[:length], nil
}

// takeCompleteBuffer returns the complete existing buffer.
// This can be used if the necessary buffer size is unknown.
