[Question] lack support for keyGet* & keyMatach4

[JalinWang]

Casbin-cpp lacks some built-in functions. Is there any plan to support them all? I'm not sure if it's worthwhile to do so :(

Full function list: https://casbin.io/docs/function

Supported functions in casbin-cpp: (no keyGet* & keyMatach4)

namespace casbin {

// KeyMatch determines whether key1 matches the pattern of key2 (similar to RESTful path), key2 can contain a *.
// For example, "/foo/bar" matches "/foo/*"
bool KeyMatch(const std::string& key1, const std::string& key2);

// KeyMatch2 determines whether key1 matches the pattern of key2 (similar to RESTful path), key2 can contain a *.
// For example, "/foo/bar" matches "/foo/*", "/resource1" matches "/:resource"
bool KeyMatch2(const std::string& key1, const std::string& key2);

// KeyMatch3 determines whether key1 matches the pattern of key2 (similar to RESTful path), key2 can contain a *.
// For example, "/foo/bar" matches "/foo/*", "/resource1" matches "/{resource}"
bool KeyMatch3(const std::string& key1, const std::string& key2);

// RegexMatch determines whether key1 matches the pattern of key2 in regular expression.
bool RegexMatch(const std::string& key1, const std::string& key2);

// IPMatch determines whether IP address ip1 matches the pattern of IP address ip2, ip2 can be an IP address or a CIDR pattern.
// For example, "192.168.2.123" matches "192.168.2.0/24"
bool IPMatch(const std::string& ip1, const std::string& ip2);

} // namespace casbin
