How can I cast Bson (vibe.d) to various struct types? The best
would be to get rid of the switch statement as well.
It works fine deserializing when casting directly
collection.findOne!UserCreate(), but when I try from a Bson
object I get below error directly.
What to do?

I want to have a array/list/queue of instances of various struct
types that represent events. How can I achieve that? With classes
I would have interfaces I guess, but I want to use structs if
possible as they seem less complex (and faster?).
Can I wrap each struct with in another struct calle

If you know all types up front you can use the Sumtype library

Thanks, it's a good starting point, the best would be if I only
needed to define that the struct would implement void applyTo(ref

If all of the structs need to implement a particular method (or

How can I initialize my two dimensional array?
When I try to run the code below I get the error:

I'm experimenting with generating wasm files with ldc2 but I'm
having problems when trying to pass JavaScript Objects and
receive them as structs and the other way around.
I found this super nice getting started guide that works fine for
basic types like double and so on
