Types

type ProviderQueryManager

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

ProviderQueryManager manages requests to find more providers for blocks for bitswap sessions. It's main goals are to: - rate limit requests -- don't have too many find provider calls running simultaneously - connect to found peers and filter them if it can't connect - ensure two findprovider calls for the same block don't run concurrently - manage timeouts

func New

func New(ctx context.Context, network ProviderQueryNetwork) *ProviderQueryManager

New initializes a new ProviderQueryManager for a given context and a given network provider.

func (*ProviderQueryManager) FindProvidersAsync

func (pqm *ProviderQueryManager) FindProvidersAsync(sessionCtx context.Context, k cid.Cid) <-chan peer.ID

FindProvidersAsync finds providers for the given block.

func (*ProviderQueryManager) SetFindProviderTimeout

func (pqm *ProviderQueryManager) SetFindProviderTimeout(findProviderTimeout time.Duration)

SetFindProviderTimeout changes the timeout for finding providers

func (*ProviderQueryManager) Startup

func (pqm *ProviderQueryManager) Startup()

Startup starts processing for the ProviderQueryManager.

type ProviderQueryNetwork

type ProviderQueryNetwork interface {
	ConnectTo(context.Context, peer.ID) error
	FindProvidersAsync(context.Context, cid.Cid, int) <-chan peer.ID
}

ProviderQueryNetwork is an interface for finding providers and connecting to peers.
