Functions ¶
func ByteArrayComparator ¶
Compares two byte arrays for sorting purposes. Return: true if a should come first in ascending order, false otherwise.
func ByteArrayContains ¶
Returns true if the given array of byte arrays contains lookFor
func ByteArrayCopy ¶
Make a clean copy of the <source> byte array with the given length to reduce memory footprint.
func DoubleSha256 ¶
func DownloadFile ¶
Download a file via http(s) and store it locally.
func FileDoesNotExists ¶
FileDoesNotExists returns 'true' if we can safely assume that the given file does not exist.
func IsPrivateIP ¶
func StringToFile ¶
