Public Member Functions
	LengthParserImpl (std::string_view str, LengthParser::Options options)
	Construct a new LengthParser implementation object.

ParseResult< LengthParser::Result >	parse ()
	Parse a length and return the result or error.

bool	unitRequired (double number) const
	Check if a unit is required for the given number.

Public Member Functions inherited from donner::base::parser::ParserBase
	ParserBase (std::string_view str)
	Create a new parser.

Additional Inherited Members
Protected Member Functions inherited from donner::base::parser::ParserBase
std::string_view	take (size_t count)
	Removes and returns count characters from the remaining string.

void	skipWhitespace ()
	Remove whitespace characters, from the front of `remaining_` if they exist, where whitespace is based on the result of isWhitespace().

void	skipCommaWhitespace ()
	Remove whitespace characters and up to one ',' character from the front of `remaining_` if they exist.

bool	isWhitespace (char ch) const
	Returns if the character is whitespace, where whitespace is defined as being either U+000A LINE FEED, U+000D CARRIAGE RETURN, U+0009 CHARACTER TABULATION, or U+0020 SPACE.

FileOffset	currentOffset (int index=0) const
	Return the location of the parser's cursor, in characters from the start of the screen.

size_t	consumedChars () const
	Returns the number of characters consumed by the parser.

ParseResult< double >	readNumber ()
	Read a number, note that this does not skip whitespace.

std::optional< ParseError >	readNumbers (std::span< double > resultStorage)
	Read `resultStorage.size()` numbers, separated by whitespace and an optional comma.

Protected Attributes inherited from donner::base::parser::ParserBase
const std::string_view	str_
	The original string.

std::string_view	remaining_
	A slice of the remaining characters to parse within str_.
