Nevermind, this works:
return !flux::ref(mappingsList).any(flux::proj([](const auto vk) { return vk == 0; },&CBActionMap::ButtonVirtualKeycode));
Replacing some of my ranges filter stuff with flux made it around 25% faster
That's great to hear!
Documentation doesn't really refer to flux::proj() much at all, beyond a couple instances of it's usage.
Yeah, there's lots of stuff missing from the documentation at the moment, it definitely needs improvement

Glad to hear you figured it out! If you're interested, I think the following should be equivalent but is a bit shorter and perhaps more readable: (the generated code should be the same though)
return flux::all(mappingsList, flux::proj(flux::pred::nonzero, &CBActionMap::ButtonVirtualKeycode));
If you have any more questions about Flux please let me know :)
Replacing some of my ranges filter stuff with flux made it around 25% faster, but I am unable to use flux::proj() for a projection with any():
return ! std::ranges::any_of(mappingsList, [](const auto vk) { return vk == 0; }, &CBActionMap::ButtonVirtualKeycode);
attempt:return !flux::ref(mappingsList).any([](const auto vk) { return vk == 0; }, flux::proj(std::equal{}, &CBActionMap::ButtonVirtualKeycode));
