I created a nogc array handler struct, and I would like to use

I can only easily find anything related to it for simple

slices directly, it would be a great help (lock write access in
a `synchronized` scope, then only read from the slice).
Your question is not very clear.
You cannot find anything related to what? To using `shared`?
You also didn't clarify what you mean by 'use it as a shared
array'. Do you mean you want to make an instance of your struct
`shared`? You can do that by casting it to `shared` and away from
`shared` (as long as you manually ensure thread safety with
mutexes, or simply pass it to a different thread and discard the
original):
```d
struct S{}
shared S s;
void main(){
S sLocal;
s = cast(shared)sLocal;
}
```
If you're asking how you can make your implementation `shared`,
that's much more complicated and I wouldn't recommend it unless
you know what you're getting into. `shared` functions are rarely
implemented outside of things like synchronisation primitives
(e.g. mutexes).
