storablevector Data.StorableVector.ST.Lazy

storablevector Data.StorableVector.ST.Strict
VS.unpack $ runSTVector (do arr <- new 10 'a'; Monad.mapM_ (\n -> modify arr (mod n 8) succ) [0..10]; return arr)
unsafeModify :: Storable e => Vector s e -> Int -> (e -> e) -> ST s ()
storablevector Data.StorableVector.ST.Lazy Data.StorableVector.ST.Strict
maybeModify :: Storable e => Vector s e -> Int -> (e -> e) -> ST s Bool
storablevector Data.StorableVector.ST.Strict
Similar to maybeWrite. In future maybeModify will replace modify.
