func HTTPRequest 

func HTTPRequest(reqConfig *ReqConfig, respObj interface{}) (*http.Response, error)

HTTPRequest queries the API provided in the ReqConfig object and converts the returned json(Byte data) into an respObj interface. Returned http response body is usually empty because the http stream cannot be read twice.

func IsOnline 

func IsOnline() bool

LTCChainParams returns the network parameters from the LTC chain provided a network type is given.

func NetDir 

func NetDir(assetType AssetType, netType NetworkType) string

NetDir returns data directory name for a given asset's type and network connected. If "unknown" is returned, unsupported asset type or network was detected.

func NormalizeAddress 

func NormalizeAddress(addr string, defaultPort string) (string, error)

func ShannonEntropy 

func ShannonEntropy(text string) (entropy float64)

func ShutdownHTTPClients 

func ShutdownHTTPClients()

ShutdownHTTPClients shutdowns any active connection by cancelling the context.

func TranslateError 

func TranslateError(err error) error

todo, should update this method to translate more error kinds.

func TranslateNetworkError 

func TranslateNetworkError(host string, errMsg error) error

func TrimNonAphaNumeric
