Timeout with restc-cpp

Question

I have the following code to execute a PUT to a given address by means of the restc-cpp library:

auto rest_client = RestClient::Create();

auto done = rest_client->ProcessWithPromise([&mess,AI_IP,AI_port,Auth_token](Context& ctx){

auto reply = RequestBuilder(ctx).Put("http://ip_address:port/").Data(message).Execute();

});

try
{
    done.get();
}
catch(const exception& ex)
{
    ...
}
catch(const boost::exception& ex)
{
    ...
}
RESTC_CPP_IN_COROUTINE_CATCH_ALL
{
    ...
}

I would like to set a timeout for the execution of this PUT, but I do not find anything for this in the documentation of restc-cpp. Do you know how to do this? Thanks

Sidenote: I'd expect boost::exception to inherit from std::exception, and if it does, you will never catch a boost::exception if you place that after std::exception like you now do. That is, if exception is really std::exception. It's impossible to tell from your code snippet. — Ted Lyngmo

You can use Request::Properties to set timeouts on individual requests:

auto rest_client = RestClient::Create();

auto done = rest_client->ProcessWithPromise([&mess, AI_IP, AI_port, Auth_token](Context& ctx){
    
    restc_cpp::Request::Properties properties;
    properties.sendTimeoutMs = 30000;  // 30 seconds in milliseconds
    properties.recvTimeout = 30000;    // 30 seconds in milliseconds
    
    auto reply = RequestBuilder(ctx)
        .Put("http://ip_address:port/")
        .Data(message)
        .Properties(properties)
        .Execute();
});

try {
    done.get();
}
catch(const exception& ex) {
    // timeout exceptions will get caught here
}

See the Properties Struct in the headers here for all the configs: https://github.com/jgaa/restc-cpp/blob/master/include/restc-cpp/restc-cpp.h#L168

int sendTimeoutMs = (1000 * 12);  // For each IO operation
int replyTimeoutMs = (1000 * 21); // For the reply header
int recvTimeout = (1000 * 21);    // For each IO operation
