Functions

func AppendIfMissing

func AppendIfMissing(slice []string, i string) []string

AppendIfMissing Append only if the item does not exists in the current list

func CompareList

func CompareList(a, b []string) []string

CompareList Compare two lists and return a list with the difference

func DestAddrs

func DestAddrs(ctx context.Context, host string, resolver *net.Resolver, timeout time.Duration) ([]string, error)

DestAddrs resolve the hostname to all it'ss IP's

func HasListDuplicates

func HasListDuplicates(m []string) (string, error)

HasListDuplicates Find duplicates in a list

func HasMapDuplicates

func HasMapDuplicates(m map[string]string) bool

HasMapDuplicates Find duplicates in a map keys

func IsEqualIP

func IsEqualIP(ips1, ips2 string) bool

IsEqualIP IP Comparison

func SrvRecordCheck

func SrvRecordHosts

func SrvRecordHosts(record string) ([]string, error)

func Time2Float

func Time2Float(t time.Duration) float32

Time2Float Convert time to float32

func TimeAverage

func TimeAverage(values []time.Duration) float64

TimeAverage Calculates the average of a slice of durations

func TimeCorrectedDeviation

func TimeCorrectedDeviation(values []time.Duration) float64

TimeCorrectedDeviation Calculates standard deviation using Bessel's correction which uses n-1 in the SD formula to correct bias of small sample size

func TimeRange
