parse_number()

template<typename T>

std::optional< T > reusex::utils::parse_number	(	std::string_view	s,
		std::size_t *	consumed = nullptr )

Parse a number at the start of s, after optional whitespace and a '+' (strtod accepts both; from_chars does not).

Sets consumed to the characters used (0 when there is no number). Out-of-range values are reported as no number.
