Functions

func FormatSlice

func FormatSlice(a []string) string

func HasDuplicates

func HasDuplicates(resources []string) bool

func InterfaceSlice

func InterfaceSlice(slice interface{}) []interface{}

InterfaceSlice converts any interface{} into a []interface{} slice

func ToPointer

func ToPointer(v interface{}) interface{}

ToPointer takes an interface{} object and will return a pointer to this object if the object is not already a pointer. Otherwise, it will return the original value. It is safe to typecast the return-value of GetPointer into a pointer of the right type, except in very special cases (such as passing in nil without an explicit type)

func ToStringSliceE

func ToStringSliceE(i interface{}) ([]string, error)

func TryAcquireMax

func TryAcquireMax(ctx context.Context, sem *semaphore.Weighted, n int64) (int64, error)

SemaphoreAcauireMax is calling TryAcquire with 1 until it fails and return n-TryAcquireSucess

func Uint64ToInt

func Uint64ToInt(i uint64) int

func Uint64ToInt64

func Uint64ToInt64(i uint64) int64

Uint64ToInt64 if value is bigger than math.MaxInt64 return math.MaxInt64 otherwise returns original value casted to int64
