Struct debris_llir::type_context::TypeContext

pub struct TypeContext {
    cache: RefCell<FxHashMap<TypeId, ClassRef>>,
    null: OnceCell<ObjectRef>,
    never: OnceCell<ObjectRef>,
}

Caches all classes. Could maybe be used as an arena in the future in cases the Rc design is not fast enough. TODO: Right now the stored classes create cycles which lead to memory leaks. This should be fixed quickly.

Fields

cache: RefCell<FxHashMap<TypeId, ClassRef>>

Cache for classes

The key is the type of the Payload Struct.

null: OnceCell<ObjectRef>

The null singleton

never: OnceCell<ObjectRef>

The never singleton
