Marshaling

pack :: (Reference (Rep a), Marshal a) => a -> IO (Ref (Rep a))

Pack a value into its runtime representation

 pack a = to a >>= ref

unpack :: (Reference (Rep a), Marshal a) => Ref (Rep a) -> IO a

Unpack a value from its runtime representation

 unpack a = deref a >>= from

class Reference a where

Optionally make a refrence of a value

Associated Types

type Ref a :: *

The type of a referenced value

Methods

ref :: a -> IO (Ref a)

Convert to a referenced value

deref :: Ref a -> IO a
