Documentation
data UnliftedArray e #
Immutable arrays that efficiently store types that are simple wrappers around unlifted primitive types. The values of the unlifted type are stored directly, eliminating a layer of indirection.

class PrimUnlifted a where #
Classifies the types that are able to be stored in UnliftedArray and
MutableUnliftedArray. These should be types that are just liftings of the
unlifted pointer types, so that their internal contents can be safely coerced
into an ArrayArray#.

unsafeNewUnliftedArray :: (HasCallStack, PrimMonad m) => Int -> m (MutableUnliftedArray (PrimState m) a) Source #
newUnliftedArray :: (HasCallStack, PrimMonad m, PrimUnlifted a) => Int -> a -> m (MutableUnliftedArray (PrimState m) a) Source #
Arguments
| :: (PrimMonad m, PrimUnlifted a) | |
| => MutableUnliftedArray (PrimState m) a | destination |
| -> a | value to fill with |
| -> m () |
Sets all the positions in an unlifted array to the designated value.
sizeofUnliftedArray :: UnliftedArray e -> Int #
Yields the length of an UnliftedArray.
sizeofMutableUnliftedArray :: MutableUnliftedArray s e -> Int #
Yields the length of a MutableUnliftedArray.
readUnliftedArray :: (HasCallStack, PrimMonad m, PrimUnlifted a) => MutableUnliftedArray (PrimState m) a -> Int -> m a Source #
writeUnliftedArray :: (HasCallStack, PrimMonad m, PrimUnlifted a) => MutableUnliftedArray (PrimState m) a -> Int -> a -> m () Source #
indexUnliftedArray :: (HasCallStack, PrimUnlifted a) => UnliftedArray a -> Int -> a Source #
indexUnliftedArrayM :: (HasCallStack, Monad m, PrimUnlifted a) => UnliftedArray a -> Int -> m a Source #
unsafeFreezeUnliftedArray :: PrimMonad m => MutableUnliftedArray (PrimState m) a -> m (UnliftedArray a) #
Freezes a MutableUnliftedArray, yielding an UnliftedArray. This simply
marks the array as frozen in place, so it should only be used when no further
modifications to the mutable array will be performed.

sameMutableUnliftedArray :: MutableUnliftedArray s a -> MutableUnliftedArray s a -> Bool #
