Functions

func ClearSignals

func ClearSignals(c chan<- os.Signal)

ClearSignals clears any signals that have been registered on the provided channel and closes the channel.

func CopyBytes

func CopyBytes(b []byte) []byte

CopyBytes returns a copy of the provided byte slice. If nil is provided, nil will be returned.

func HandleSignals

func HandleSignals(f func(os.Signal), sigs ...os.Signal) chan<- os.Signal

HandleSignals calls f if the go runtime receives the any of the provided signals with the received signal.

If f is nil or there are no provided signals, then nil will be returned. Otherwise, a signal channel will be returned that can be used to clear the signals registed by this function by valling ClearSignals.

func IsSortedAndUnique

func IsSortedAndUnique(data sort.Interface) bool

IsSortedAndUnique returns true if the elements in the data are unique and sorted.

func IsSortedAndUniqueUint32

func IsSortedAndUniqueUint32(u32 []uint32) bool

IsSortedAndUniqueUint32 returns true if the array of uint32s are sorted and unique

func SortUint32

func SortUint32(u32 []uint32)

SortUint32 sorts an uint32 array
