[Variant] Minimum implementation to be variant friendly
Hello, What's the minimum implementation a struct needs to fulfill in order to be boost::variant friendly? Things like, does it need to support perfect forwarding? An assignment operator? And so on. Thanks! Michael Powell

What do you mean by "boost::variant friendly" ?
Thanks!

What else would it mean? Absent errors and so forth. What is the minimum implementation footprint that a struct (or class) need to implement?
Thanks!
