fromForeignPtr :: Shape sh => sh -> ForeignPtr e -> Array F sh e #

O(1). Wrap a ForeignPtr as an array.

toForeignPtr :: Array F sh e -> ForeignPtr e #

O(1). Unpack a ForeignPtr from an array.

computeIntoS :: (Load r1 sh e, Storable e) => ForeignPtr e -> Array r1 sh e -> IO () #

Compute an array sequentially and write the elements into a foreign buffer without intermediate copying. If you want to copy a pre-existing manifest array to a foreign buffer then delay it first.

computeIntoP :: (Load r1 sh e, Storable e) => ForeignPtr e -> Array r1 sh e -> IO () #

Compute an array in parallel and write the elements into a foreign buffer without intermediate copying. If you want to copy a pre-existing manifest array to a foreign buffer then delay it first.
