coro_rpc简介 示例代码错误

https://alibaba.github.io/yalantinglibs/zh/coro_rpc/coro_rpc_introduction.html

#include "rpc_service.hpp"
#include

using namespace coro_rpc;
using namespace async_simple::coro;

Lazy test_client() {
coro_rpc_client client;
co_await client.connect("localhost", /*port =*/"9000");
auto r = co_await client.call("hello coro_rpc"); //传参数调用rpc函数
std::cout << r.result.value() << "\n"; //will print "hello coro_rpc"
}

int main() {
syncAwait(test_client());
}

错误行
std::cout << r.result.value() << "\n"; //will print "hello coro_rpc"
r.result.value()改为r.value()后可以运行

Open the coro_rpc introduction example at the linked documentation page and inspect the client call result usage. Update the output expression to match the runnable result API, then verify that the example runs and prints "hello coro_rpc".
