Functions

func CidFromNamespacedSha256

func CidFromNamespacedSha256(namespacedHash []byte) (cid.Cid, error)

CidFromNamespacedSha256 uses a hash from an nmt tree to create a CID

func GetNode

func GetNode(ctx context.Context, bGetter blockservice.BlockGetter, root cid.Cid) (ipld.Node, error)

func MustCidFromNamespacedSha256

func MustCidFromNamespacedSha256(hash []byte) cid.Cid

MustCidFromNamespacedSha256 is a wrapper around cidFromNamespacedSha256 that panics in case of an error. Use with care and only in places where no error should occur.

func NamespacedSha256FromCID

func NamespacedSha256FromCID(cid cid.Cid) []byte

NamespacedSha256FromCID derives the Namespaced hash from the given CID.

func NewNMTLeafNode

func NewNMTLeafNode(id cid.Cid, data []byte) ipld.Node

func NewNMTNode

func NewNMTNode(id cid.Cid, l, r []byte) ipld.Node

func NewNamespaceHasher

func NewNamespaceHasher(hasher *nmt.Hasher) hash.Hash

func RandNamespacedCID

func RandNamespacedCID(t *testing.T) cid.Cid
