func New

func New(wsEndpointURL, rpcEndpointURL string) CybexAPI

New creates a new CybexAPI interface. wsEndpointURL: Is a mandatory websocket node URL. rpcEndpointURL: Is an optional RPC endpoint to your local `cli_wallet`. The use of wallet functions without this argument will throw an error. If you do not use wallet API, provide an empty string.

func NewWithAutoEndpoint

func NewWithAutoEndpoint(startupEndpointURL, rpcEndpointURL string) (CybexAPI, error)

NewWithAutoEndpoint creates a new CybexAPI interface with automatic node latency checking. It's best to use this API instance type for a long API lifecycle because the latency tester takes time to unleash its magic. startupEndpointURL: Iss a mandatory websocket node URL to startup the latency tester quickly. rpcEndpointURL: Is an optional RPC endpoint to your local `cli_wallet`. The use of wallet functions without this argument will throw an error. If you do not use wallet API, provide an empty string.

type ErrorFunc

type ErrorFunc func(error)

type LatencyTester

type LatencyTester interface {
	Start()
	Close() error
	String() string
