Types

type AsyncMultiDriver added in v2.149.0 

type AsyncMultiDriver struct{ MultiDriver }

type AsyncableDriver added in v2.149.0 

type AsyncableDriver interface {
	// AsyncableDriver implements Driver to simplify the creation pipeline.
	// Creator returns AsyncableDriver so that fit both cases.
	Driver

	// FindPeersAsync works differently than FindPeers.
	// FindPeersAsync is not expected to close the chan.
	// Also it's expected to start a goroutine to run the expensive part of the search.
	// And it's only when the caller have received enough valid peers he shutdown the search canceling the context.
	FindPeersAsync(context.Context, chan<- peer.AddrInfo, string, ...discovery.Option) error
}

AsyncableDriver allows MultiDriver to reuse the same chan for multiple drivers.

func NewAsyncMultiDriver added in v2.149.0 

func NewAsyncMultiDriver(logger *zap.Logger, drivers ...AsyncableDriver) AsyncableDriver

func NewMockedDriverClient 

func NewMockedDriverClient(host p2p_host.Host, server *MockDriverServer) AsyncableDriver

type MultiDriver 

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

MultiDriver is a simple driver manager, that forward request across multiple driver

func (*MultiDriver) Advertise 

func (md *MultiDriver) Advertise(ctx context.Context, ns string, opts ...p2p_discovery.Option) (time.Duration, error)

Advertise simply dispatch Advertise request across all the drivers

func (*MultiDriver) FindPeers

func (md *MultiDriver) FindPeersAsync(ctx context.Context, outPeers chan<- p2p_peer.AddrInfo, ns string, opts ...p2p_discovery.Option) error

FindPeersAsync expect the caller to use it asynchronously and cancel the context with enough peers or found (or deadline exceeded). If the context is not canceled the search will go indefinitely.
