Struct RefType 

pub struct RefType(/* private fields */);

A WebAssembly reference type.

Packed as:

[nullable:1 concrete:1 payload:30]

For concrete types, payload is a module type index before instantiation and a canonical store type address at runtime. Otherwise, it is an AbstractHeapType.

See https://webassembly.github.io/spec/core/syntax/types.html#syntax-reftype
