anyref property
Field for when this val is a WebAssembly anyref value.
If this is set to 0 then it's a null anyref, otherwise this must be
passed to wasmtime_anyref_from_raw to determine the
wasmtime_anyref_t.
Note that this field is always stored in a little-endian format.
Implementation
@ffi.Uint32()
external int anyref;
