boost::unordered_map try_emplace

[dkabrane@…]

Is there something planned to implement C++17 try_emplace function in unordered_map (and other unordered associative containers) ?

I'm working on it, although only unordered_map has try_emplace. It might be in 1.64.0.

You're right, it's only for unordered_map, my bad I thought it was common to every associative container. I'm eager to test it.

actually boost::container::map does have try_emplace so it will be great to have it in boost::unordered_map as well.
