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)

GenerateMultiAddrFromString is used to take a string, and convert it to a multiformat based address

func ParseMultiAddrForIPFSPeer ¶ added in v1.0.6

func ParseMultiAddrForIPFSPeer(address ma.Multiaddr) (bool, error)

ParseMultiAddrForIPFSPeer is used to parse a multiaddress to determine whether its a valid ipfs address

func ParsePeerIDFromIPFSMultiAddr ¶

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

ParsePeerIDFromIPFSMultiAddr is used to parse a multiaddress and extract the IPFS peer id

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
