I would like to replicate this type in C:

struct IFoo *FooTable[256];

Right now, I have something like this:

struct MyThing<'a> {
    foo_table: [Option<Rc<&'a dyn FooTrait>>; 256],
}

However, I'm getting just a ton of errors when attempting to manipulate this field. Too many to list here, which indicates that after years of working with Rust, I still don't understand how to make an entity that can have several pointers to it.

What am I doing wrong? To me the above type makes perfect sense:

• Optional<>, because it's potentially NULLable.
• Rc<>, because it's reference counted.
• &'a dyn FooTrait because it's a Trait Object (yes, by intention).

I don't understand what else I could possibly need here? Any elucidation would be very helpful, thanks!

EDIT: I forgot to mention that I've also been searching the web for help on this and trying my best to RTFM, but to no avail. Despite there being a ton of sites that cover things like Rc vs Arc, etc, I'm still not able to find a site that clearly illustrates the simple use-case of having a structure with n pointers to it from different places/scopes.
