deref :: forall eff ref s a. (IvoryStore a, IvoryVar a, IvoryVar (ref s (Stored a)), IvoryRef ref) => ref s (Stored a) -> Ivory eff a Source
Dereferenceing.
refCopy :: forall eff sTo ref sFrom a. (IvoryRef ref, IvoryVar (Ref sTo a), IvoryVar (ref sFrom a), IvoryArea a) => Ref sTo a -> ref sFrom a -> Ivory eff () Source
Memory copy. Emits an assertion that the two references are unequal.
class IvoryVar a => IvoryStore a Source
Things that can be safely stored in references.
