Thanks for a really good explanation, passing pointers over the

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

How can I initialize my two dimensional array?
When I try to run the code below I get the error:
Error: non-constant expression ["user":[cast(Capability)0],
"administrator":[cast(Capability)1]]
Code:
enum Capability {
self,
administer
}

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

I want to have a array/list/queue of instances of various struct

I would have interfaces I guess, but I want to use structs if

Can I wrap each struct with in another struct calle
How can I cast Bson (vibe.d) to various struct types? The best

It works fine deserializing when casting directly

What to do?
