lut_chars(
const char* s) noexcept;
Declared in file <boost/url/grammar/lut_chars.hpp> at line 188
This function constructs a character set which has as members, all of the characters present in the null-terminated string `s`.
constexpr lut_chars digits = "0123456789";
Linear in `::strlen(s)`, or constant if `s` is a constant expression.
Throws nothing.
