Functions

func AdjustRateInterval

func AdjustRateInterval(namespaceCreationTime time.Time, queryTime time.Time, ratesInterval string) (string, error)

func CryptoRandomBytes

func CryptoRandomBytes(n int) ([]byte, error)

CryptoRandomBytes returns securely generated random bytes. It will return an error if the system's secure random number generator fails to function correctly, in which case the caller should not continue.

func CryptoRandomString

func CryptoRandomString(n int) (string, error)

CryptoRandomString returns a securely generated random string. It will return an error if the system's secure random number generator fails to function correctly, in which case the caller should not continue.

func GetStartTimeForRateInterval

func GetStartTimeForRateInterval(baseTime time.Time, rateInterval string) (time.Time, error)

func RandomString

func RandomString(n int) string

RandomString generates a random string of length n. Before calling this function, you should call rand.Seed() to initialize the default source.

func RemoveNilValues

func RemoveNilValues(root interface{})

Types

type ClockMock

type ClockMock struct {
	Time time.Time
}

func (ClockMock) Now

func (clock ClockMock) Now() time.Time

type Errors

type Errors struct {
	// contains filtered or unexported fields
}

Errors is a struct implementing error interface, allowing to accumulate several errors as a flat list
