	// belongs to this decoder, or an error if the data could not be read or is ambiguous.
	// Unknown is true if the data could not be determined to match the decoder type.
	// Decoders should assume that they can read as much of peek as they need (as the caller
	// provides) and may return unknown if the data provided is not sufficient to make a
	// a determination. When peek returns EOF that may mean the end of the input or the
	// end of buffered input - recognizers should return the best guess at that time.
