[Variant] Bug assigning similar, but different concrete types during assignment / ctor relay
by Michael Powell 18 Nov '18

18 Nov '18

Hello, I've got a Boost.Variant confusion going on during ctor relay. I have two types participating in the Variant, an Integer type and a Floating Point type. Both are Numeric as a base class. i.e. something like: template<typename T> struct numeric {}; struct integer : numeric<long> {}; struct floating_point : numeric<double> {}; Then: using constant_value = boost::variant<..., floating_point, integer, ...>; Somewhere during the handling, I have a test case in which I have a constant_value{} starting out in life as an integer{}. However, somewhere during handling, variant is misinterpreting integer (which=3) as a floating_point (which=2). This is incorrect, of course. I could force the issue, I suppose and re-set the value to the integer, but I'd like to understand the issue. I think it's a bug in variant, or perhaps a "feature" confusing integer with floating_point along base class numeric lines? Any ideas

[Optional] Lazy initialized optional
by Michael Powell 14 Nov '18

14 Nov '18

Hello, I am looking into deriving from boost::optional and adding lazy initialization capability. I can arrange a constructor, or whatever, to inject an appropriate factory method, functional callback, etc, that's no problem. >From the boost::optional perspective, I'd like to override a key method (or methods, hopefully not too many) in order to inject that factory provided value. I'm thinking optional::get? Unless there's a better override for that? Cheers, Michael Powell
