DedupKey(requestID graphsync.RequestID, key string)
IgnoreBlocks(requestID graphsync.RequestID, links []ipld.Link)
SendResponse(
requestID graphsync.RequestID,
link ipld.Link,
data []byte,
notifees ...notifications.Notifee,
) graphsync.BlockData
SendExtensionData(graphsync.RequestID, graphsync.ExtensionData, ...notifications.Notifee)
FinishWithCancel(requestID graphsync.RequestID)
FinishRequest(requestID graphsync.RequestID, notifees ...notifications.Notifee) graphsync.ResponseStatusCode
FinishWithError(requestID graphsync.RequestID, status graphsync.ResponseStatusCode, notifees ...notifications.Notifee)
// Transaction calls multiple operations at once so they end up in a single response
// Note: if the transaction function errors, the results will not execute
Transaction(requestID graphsync.RequestID, transaction Transaction) error
PauseRequest(requestID graphsync.RequestID, notifees ...notifications.Notifee)
}
