Functions

func ArrComp

func ArrComp(a, b []byte) error

ArrComp checks if two byte slices are the same.

func GetDAGServ

func GetDAGServ() ipld.DAGService

GetDAGServ returns a mock DAGService.

func GetEmptyNode

func GetEmptyNode(t testing.TB, dserv ipld.DAGService, opts NodeOpts) ipld.Node

GetEmptyNode returns an empty unixfs file node.

func GetNode

func GetNode(t testing.TB, dserv ipld.DAGService, data []byte, opts NodeOpts) ipld.Node

GetNode returns a unixfs file node with the specified data.

func GetRandomNode

func GetRandomNode(t testing.TB, dserv ipld.DAGService, size int64, opts NodeOpts) ([]byte, ipld.Node)

GetRandomNode returns a random unixfs file node.

func PrintDag

func PrintDag(nd *mdag.ProtoNode, ds ipld.DAGService, indent int)

PrintDag pretty-prints the given dag to stdout.

func SizeSplitterGen

func SizeSplitterGen(size int64) chunker.SplitterGen

SizeSplitterGen creates a generator.

Types

type NodeOpts

type NodeOpts struct {
	Prefix cid.Prefix
	// ForceRawLeaves if true will force the use of raw leaves
	ForceRawLeaves bool
	// RawLeavesUsed is true if raw leaves or either implicitly or explicitly enabled
	RawLeavesUsed bool
	// Enables reed solomon splitter
	ReedSolomonEnabled bool
	// Enables balanced DAG to be used than trickle.
	Balanced bool
	// contains filtered or unexported fields
}

NodeOpts is used by GetNode, GetEmptyNode and GetRandomNode

func UseBalancedWithMetadata

func UseBalancedWithMetadata(mdata []byte, chkSize uint64) NodeOpts

func UseReedSolomon

func UseReedSolomon(numData, numParity uint64, mdata []byte, chkSize uint64) NodeOpts
