// Size is the number of bytes available for reading via [Reader.ReadAt].
// The returned value is always the same and is not affected by calls
// to any other method.

// Read implements the [io.Reader] interface.
func (r *Reader) Read(b []byte) (n int, err error) { … }

// ReadAt implements the [io.ReaderAt] interface.

// Reset resets the [Reader] to be reading from s.
func (r *Reader) Reset(s string) { … }

// NewReader returns a new [Reader] reading from s.
// It is similar to [bytes.NewBufferString] but more efficient and non-writable.
