Compares two paths lexicographically.
1) Checks whether
lhs and rhs are equal. Equivalent to !(lhs < rhs) && !(rhs < lhs).2) Checks whether
lhs and rhs are not equal. Equivalent to !(lhs == rhs).3) Checks whether
lhs is less than rhs. Equivalent to lhs.compare(rhs) < 0.4) Checks whether
lhs is less than or equal to rhs. Equivalent to !(rhs < lhs).5) Checks whether
lhs is greater than rhs. Equivalent to rhs < lhs.6) Checks whether
lhs is greater than or equal to rhs. Equivalent to !(lhs < rhs).7) Obtains the three-way comparison result of
lhs and rhs. Equivalent to lhs.compare(rhs) <=> 0.These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::filesystem::path is an associated class of the arguments. This prevents undesirable conversions in the presence of a using namespace std::filesystem; using-directive.
