func DialWithClient

func (*HttpConn) CallContext

func (h *HttpConn) CallContext(ctx context.Context, result interface{}, op Operation) error

CallContext performs a JSON-RPC call with the given arguments. If the context is canceled before the call has successfully returned, CallContext returns immediately.

The result must be a pointer so that package json can unmarshal into it. You can also pass nil, in which case the result is ignored.
