Functions

func ApplyConfig

func ApplyConfig(config IDNSConfig) error

func ClearDNSCache

func ClearDNSCache()

func CloseGeoDB

func CloseGeoDB() error

func GeoLookUp

func GeoLookUp(ip string) (countryCode string)

func InitDNSCache

func InitDNSCache()

func InitGeoIP

func InitGeoIP(dbFile string) error

func Pop

func Pop(h heap.Interface) interface{}

Pop removes the minimum element (according to Less) from the heap and returns it. The complexity is O(log(n)) where n = h.Len(). It is equivalent to Remove(h, 0).

func Push

func Push(h heap.Interface, x interface{})

Push pushes the element x onto the heap. The complexity is O(log(n)) where n = h.Len().
