Struct wasm_ref_t

pub struct wasm_ref_t { /* private fields */ }

*mut wasm_ref_t is a reference type (externref or funcref) for the C API.

Because we do not have a uniform representation for funcrefs and externrefs, a *mut wasm_ref_t is morally a Option<Box<Either<ExternRef, Func>>>.

A null *mut wasm_ref_t is either a null funcref or a null externref depending on context (e.g. the table’s element type that it is going into or coming out of).

Note: this is not #[repr(C)] because it is an opaque type in the header, and only ever referenced as *mut wasm_ref_t. This also lets us use a regular, non-repr(C) enum to define WasmRef.
