-- | Unboxed, multidimensional arrays based on the primitive
package.
--   
--   Provides unboxed multidimensional tables with a small interface. Comes
--   with an instance for Ix keys. Read and Show instances are provided for
--   serialization.
@package PrimitiveArray
@version 0.0.4.0


-- | Helper functions for creating new arrays.
module Data.PrimitiveArray.Internal

-- | Create a new m-array with a default value.
newWith :: Prim a => Int -> a -> ST s (MutableByteArray s)

-- | In <a>new</a>, <tt>z</tt> is not used.
new :: Prim a => Int -> a -> ST s (MutableByteArray s)


-- | Unboxed, primitive, multidimensional tables. In instance for
--   <tt>Ix</tt>-type keys comes with the package. This package trades
--   safety for speed. The index operator (!) is basically the only
--   function that does bounds-checking and only with an assertion. This,
--   however, is by design. The only way to get an immutable table from a
--   mutable one is by the <a>unsafeFreezeM</a> operation. Again, it is by
--   design that both data structures share the same memory pointer
--   internally.
--   
--   TODO We kind-of lost all but the ST monad for monadic operations.
