	parser_state (Iterator first, Sentinel last) noexcept
	parser_state (const parser_state &) noexcept=default
parser_state &	operator= (const parser_state &) noexcept=default
char	next () noexcept
	Returns the null terminator when reaching the end of the string, otherwise the next character.

	Returns the null terminator if i == e, otherwise the current character.
bool	at_end () const noexcept
	Checks whether i == e.
void	skip_whitespaces () noexcept
	Skips any whitespaces characters in the input.
bool	consume (char x) noexcept
	Tries to read x as the next character, automatically skipping leading whitespaces.
template<class Predicate >
bool	consume_if (Predicate predicate) noexcept
	Consumes the next character if it satisfies given predicate, automatically skipping leading whitespaces.
bool	consume_strict (char x) noexcept
	Tries to read x as the next character without automatically skipping leading whitespaces.
template<class Predicate >
bool	consume_strict_if (Predicate predicate) noexcept
	Consumes the next character if it satisfies given predicate without automatically skipping leading whitespaces.
auto	error ()
	Returns an error from the current state.

Public Attributes
