ffi-trait

FFI-safe traits.

#[ffi_trait]
pub trait MyTrait {
    fn a(&self);
}

...

let x: FFIDynRef<dyn MyTrait> = ...;

Notes

• This is an extreme PoC
• It probably works though
• The layout of the vtable is as discussed in RFC 2955
• Boxes dont exist yet. Please PR
• Yes, I went insane making this
• All ffi_traits must be object safe
• Self in methods support is limited. Use erased raw pointers for now. Please PR
