simple_rpc C++20 RPC库

一个高性能、易扩展的 C++20 RPC 库，支持多种通信协议和调用模式，专为现代 C++ 开发设计。 支持同步、异步调用，支持服务端和客户端，支持序列化和反序列化。

exampels

server:

void echo(RpcConnection weak, std::string sv) {
    if (auto conn = weak.lock()) {
        cout << "get connection!\n" << sv << "\n";
    } else {
        cout << "connection is nullptr\n" << sv << "\n";
    }
}

std::string helloworld(RpcConnection weak, std::string_view str) {
    if (auto conn = weak.lock()) {
        cout << "get conn\n" << str << "\n";
    } else {
        cout << "conn is nullptr\n" << str << "\n";
    }
    return std::string(str);
}


int main() {
    spdlog::set_level(spdlog::level::trace);
    Server srv("0.0.0.0", 9000);

    Router::reg_callback("echo", echo);
    Router::reg_callback("hello", helloworld);

    srv.run();
}

client:

int main(int argc, char *argv[]) {
    spdlog::set_level(spdlog::level::trace);
    try {
        Client c;
        auto fu = c.async_call("echo", std::string("hello world"));

        fu.get().as();

        auto f2 = c.async_call("hello", std::string("hello world"));
        spdlog::info("call hello");
        auto r = f2.get().unwrap<std::string>();
        spdlog::info("hello result: {}", r);
    } catch (std::exception &e) {
        spdlog::error("err: {}", e.what());
    }
}
