Variables

	ProtocolBitswapOne    protocol.ID = "/ipfs/bitswap/1.0.0"

Types

type BitSwapNetwork

type BitSwapNetwork interface {

	// SendMessage sends a BitSwap message to a peer.
	SendMessage(
		context.Context,
		peer.ID,
		bsmsg.BitSwapMessage) error

	// SetDelegate registers the Reciver to handle messages received from the
	// network.
	SetDelegate(Receiver)

	ConnectTo(context.Context, peer.ID) error

	NewMessageSender(context.Context, peer.ID) (MessageSender, error)

	ConnectionManager() ifconnmgr.ConnManager

	Stats() NetworkStats

	Routing
}

BitSwapNetwork provides network connectivity for BitSwap sessions.

func NewFromIpfsHost

func NewFromIpfsHost(host host.Host, r routing.ContentRouting) BitSwapNetwork

NewFromIpfsHost returns a BitSwapNetwork supported by underlying IPFS host.

type MessageSender

type MessageSender interface {
	SendMsg(context.Context, bsmsg.BitSwapMessage) error
	Close() error
	Reset() error
}

type NetworkStats

type NetworkStats struct {
	MessagesSent  uint64
	MessagesRecvd uint64
}

NetworkStats is a container for statistics about the bitswap network the numbers inside are specific to bitswap, and not any other protocols using the same underlying network.

type Receiver

type Receiver interface {
	ReceiveMessage(
		ctx context.Context,
		sender peer.ID,
		incoming bsmsg.BitSwapMessage)

	ReceiveError(error)

	// Connected/Disconnected warns bitswap about peer connections.
	PeerConnected(peer.ID)
	PeerDisconnected(peer.ID)
}

Implement Receiver to receive messages from the BitSwapNetwork.

type Routing

type Routing interface {
	// FindProvidersAsync returns a channel of providers for the given key.
	FindProvidersAsync(context.Context, cid.Cid, int) <-chan peer.ID

	// Provide provides the key to the network.
	Provide(context.Context, cid.Cid) error
}
