Hi Vicente, hi all,
I noticed that in the trunk there is a implementation of future<>::then(). Thank you very much for your efforts to implement it!
Hi Fernando, I have started with a restricted implementation. While trying to cover with the whole requirements I didn't reach to get correct implementation. This is way this new feature is not delivered yet. For the time been I don't think the current implementation is ready for production code.
The following example, compiles OK
boost::future <int> f1 = boost::async([]() { return 123; }); f1.then([](boost::future <int> const& f) { return std::string(""); });
But this one fails to compile: boost::future <int> f1 = boost::async([]() { return 123; }); f1.then([](boost::future <int> const& f) { });
Here future<>::then() have to returns future <void> like ...
boost::async([]() { });
Am I right?
Yes, it should. I have no access to my development environment for this week. Could you post the compiler error?
On the other hand, have you taken into account the following paper? http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3451.pdf
I read it and the mail exchanges related to this paper. Currently I didn't reached to make it working at all when the future destructor blocks, but I'm not sure this is the hidden problem as I have also other issues when the future destructor doesn't blocks. I'm really sorry that the current state is not really usable :( Best, Vicente -- View this message in context: http://boost.2283326.n4.nabble.com/future-then-Error-returning-future-void-o...
