Functions ¶
func SendMixedQuery ¶ added in v1.7.16
func SendMixedQuery( sender Sender, vdrs []ids.NodeID, numPushTo int, reqID uint32, containerID ids.ID, container []byte, )
Send a query composed partially of push queries and partially of pull queries. The validators in [vdrs] will be queried. This function sends at most [numPushTo] push queries. The rest are pull queries. If [numPushTo] > len(vdrs), len(vdrs) push queries are sent. [containerID] and [container] are the ID and body of the container being queried. [sender] is used to actually send the queries.
Types ¶

CreateStaticHandlers() (map[string]*HTTPHandler, error) // Creates the HTTP handlers for custom chain network calls. // // This exposes handlers that the outside world can use to communicate with // the chain. Each handler has the path: // [Address of node]/ext/bc/[chain ID]/[extension] // // Returns a mapping from [extension]s to HTTP handlers. // // Each extension can specify how locking is managed for convenience. // // For example, if this VM implements an account-based payments system, // it have an extension called `accounts`, where clients could get // information about their accounts.
