Functions

func CalculateGarbageCollectDate

func CalculateGarbageCollectDate(holdTimeInMonths int) time.Time

CalculateGarbageCollectDate is used to calculate the date at which a file will be removed from our inventory. To prepare data for input use `strconv.Atoi(fmt.Sprintf("%v", .....")"`

func GenerateMultiAddrFromString

func GenerateMultiAddrFromString(addr string) (ma.Multiaddr, error)

func ParsePeerIDFromIPFSMultiAddr

func ParsePeerIDFromIPFSMultiAddr(address ma.Multiaddr) (string, error)

Types

type RandomUtils

type RandomUtils struct {
	Seed       *rand.Rand
	SecureSeed *rand.Rand
}

RandomUtils is our helper struct for random related utilities

func GenerateRandomUtils

func GenerateRandomUtils() *RandomUtils

GenerateRandomUtils is used to generate our random utils struct

func (*RandomUtils) GenerateString

func (u *RandomUtils) GenerateString(length int, charset string) string

GenerateString is used to generate a fixed length random string from the specified charset, using a fresh seed each time

func (*RandomUtils) ReSeed

func (u *RandomUtils) ReSeed()

ReSeed is used to reseed our RNG
