func CompareResourceVersion ¶

func CompareResourceVersion(a, b string) (int, error)

CompareResourceVersion runs a comparison between two ResourceVersions. This only has semantic meaning when the comparison is done on two objects of the same resource. The return values are:

-1: If RV a < RV b
 0: If RV a == RV b
+1: If RV a > RV b

The function will return an error if the resource version is not a properly formatted positive integer, but has no restriction on length. A properly formatted integer will not contain leading zeros or non integer characters. Zero is also considered an invalid value as it is used as a special value in list/watch events and will never be a live resource version.
