Functions

func CidFromString

func CidFromString(c string) (cid.Cid, error)

CidFromString converts a string to a cid assuming that an empty string is cid.Undef.

func CidToString

func CidToString(c cid.Cid) string

CidToString converts a cid to string, representing cid.Undef as an empty string.

func MustParseAddr

func MustParseAddr(str string) ma.Multiaddr

MustParseAddr returns a parsed Multiaddr, or panics if invalid.

func TCPAddrFromMultiAddr

func TCPAddrFromMultiAddr(maddr ma.Multiaddr) (string, error)

TCPAddrFromMultiAddr converts a multiaddress to a string representation of a tcp address.
