pub struct wasm_ref_t { /* private fields */ }Expand description
*mut wasm_ref_t is a reference type (externref or funcref), as seen by
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 WasmRefInner.
