Constants

const SetCursorDone = "Done"

SetCursorDone is the success message returned by hcnet-core when a cursor update succeeds.

Types

type Client

type Client struct {
	// HTTP is the client to use when communicating with hcnet-core.  If nil,
	// http.DefaultClient will be used.
	HTTP HTTP

	// URL of Hcnet Core server to connect.
	URL string
}

Client represents a client that is capable of communicating with a hcnet-core server using HTTP

func (*Client) GetLedgerEntry

func (c *Client) GetLedgerEntry(ctx context.Context, ledgerKey xdr.LedgerKey) (proto.GetLedgerEntryResponse, error)

GetLedgerEntry submits a request to the hcnet core instance to get the latest state of a given ledger entry.

func (*Client) Info

func (c *Client) Info(ctx context.Context) (resp *proto.InfoResponse, err error)

Info calls the `info` command on the connected hcnet core and returns the provided response

Example

client := &Client{URL: "http://localhost:11626"}

info, err := client.Info(context.Background())

if err != nil {
	panic(err)
}

fmt.Printf("synced: %v", info.IsSynced())

func (*Client) ManualClose

func (c *Client) ManualClose(ctx context.Context) (err error)

ManualClose closes a ledger when Core is running in `MANUAL_CLOSE` mode

func (*Client) SetCursor

func (c *Client) SetCursor(ctx context.Context, id string, cursor int32) (err error)

SetCursor calls the `setcursor` command on the connected hcnet core

func (*Client) SubmitTransaction

func (c *Client) SubmitTransaction(ctx context.Context, envelope string) (resp *proto.TXResponse, err error)

SubmitTransaction calls the `tx` command on the connected hcnet core with the provided envelope

func (*Client) Upgrade

func (c *Client) Upgrade(ctx context.Context, version int) (err error)

Upgrade upgrades the protocol version running on the hcnet core instance

func (*Client) WaitForNetworkSync

func (c *Client) WaitForNetworkSync(ctx context.Context) error

WaitForNetworkSync continually polls the connected hcnet-core until it receives a response that indicated the node has synced with the network

type ClientWithMetrics

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

func NewClientWithMetrics

func NewClientWithMetrics(client Client, registry *prometheus.Registry, prometheusSubsystem string) ClientWithMetrics

func (ClientWithMetrics) SubmitTx

func (c ClientWithMetrics) SubmitTx(ctx context.Context, rawTx string) (*proto.TXResponse, error)

type HTTP

type HTTP interface {
	Do(req *http.Request) (*http.Response, error)
}

HTTP represents the http client that a hcnetcore client uses to make http requests.
