package multi
// DiscardCloser is an io.ReadWriteCloser that performs no-op operations.
//
// It implements:
// - io.Reader: Read always returns (0, nil) without reading any data
// - io.Writer: Write returns (len(p), nil) without writing any data
// - io.Closer: Close always returns nil
//
// DiscardCloser is used as a safe default input source in Multi instances
// to prevent nil pointer panics. It's similar to io.Discard but also
// implements io.ReadCloser.
//
// This type is exported for advanced use cases where a no-op ReadWriteCloser
// is needed, though most users should not need to instantiate it directly.
type DiscardCloser struct{}
// Read implements io.Reader by returning zero bytes without error.
// This allows DiscardCloser to satisfy the io.Reader interface while
// performing no actual read operation.
//
// The buffer p is not modified. This method always returns (0, nil).
func (d DiscardCloser) Read(p []byte) (n int, err error) {
return 0, nil
}
// Write implements io.Writer by accepting and discarding all data.
// It returns len(p) to indicate that all bytes were "written", but
// no data is actually stored or processed.
//
// This method always returns (len(p), nil).
func (d DiscardCloser) Write(p []byte) (n int, err error) {
return len(p), nil
}
// Close implements io.Closer with a no-op operation.
// Since DiscardCloser maintains no state and allocates no resources,
// Close simply returns nil without doing anything.
func (d DiscardCloser) Close() error {
return nil
}
