Functions

func Fingerprint

func Fingerprint(traces ptrace.Traces) (fingerprint uint64, hasError bool, err error)

Fingerprint generates a fingerprint for a set of traces. The fingerprint is a string that represents the sorted, unique paths in the traces.

If an error is returned, it will be of type Error and will indicate the problem with the trace. The fingerprint will be 0 in this case.
