OpaqueFacade

Struct OpaqueFacade

pub struct OpaqueFacade { /* private fields */ }

Expand description

A zero-sized type representing an opaque C++ object facade.

This is used as a field in Rust facade structs that represent C++ objects of unknown size. It keeps the facade struct Sized (size 0) so it can be used in FFI (thin pointers) and with generic containers like RefPtr, while ensuring LLVM knows the object has interior mutability.
