Functions

func GetterWithRandSquare

func GetterWithRandSquare(t *testing.T, n int) (share.Getter, *share.Root)

GetterWithRandSquare provides a share.Getter filled with 'n' NMT trees of 'n' random shares, essentially storing a whole square.

func Node

func Node(dn *availability_test.TestDagNet) *availability_test.TestNode

Node creates a new empty Full Node.

func RandNode

func RandNode(dn *availability_test.TestDagNet, squareSize int) (*availability_test.TestNode, *share.Root)

RandNode creates a Full Node filled with a random block of the given size.

Types

type ShareAvailability

type ShareAvailability struct {
	// contains filtered or unexported fields
}

ShareAvailability implements share.Availability using the full data square recovery technique. It is considered "full" because it is required to download enough shares to fully reconstruct the data square.

func NewShareAvailability

func NewShareAvailability(
	store *eds.Store,
	getter share.Getter,
	disc *discovery.Discovery,
) *ShareAvailability

NewShareAvailability creates a new full ShareAvailability.

func TestAvailability

func TestAvailability(t *testing.T, getter share.Getter) *ShareAvailability

func (*ShareAvailability) SharesAvailable

func (fa *ShareAvailability) SharesAvailable(ctx context.Context, header *header.ExtendedHeader) error

SharesAvailable reconstructs the data committed to the given Root by requesting enough Shares from the network.

func (*ShareAvailability) Start

func (fa *ShareAvailability) Start(context.Context) error

func (*ShareAvailability) Stop

func (fa *ShareAvailability) Stop(context.Context) error
