Data.Primitive.Contiguous

The contiguous typeclass parameterises over a contiguous array type. This allows us to have a common API to a number of contiguous array types and their mutable counterparts.

Accessors

Length Information

size :: (Contiguous arr, Element arr b) => arr b -> Int

The size of the array

sizeMutable :: (Contiguous arr, PrimMonad m, Element arr b) => Mutable arr (PrimState m) b -> m Int

The size of the mutable array

null :: Contiguous arr => arr b -> Bool

Test whether the array is empty.

Indexing

index :: (Contiguous arr, Element arr b) => arr b -> Int -> b

Index into an array at the given index.

index# :: (Contiguous arr, Element arr b) => arr b -> Int -> (#b#)

Index into an array at the given index, yielding an unboxed one-tuple of the element.

read :: (Contiguous arr, PrimMonad m, Element arr b) => Mutable arr (PrimState m) b -> Int -> m b

Read a mutable array at the given index.

Monadic indexing

indexM :: (Contiguous arr, Element arr b, Monad m) => arr b -> Int -> m b

Indexing in a monad.

The monad allows operations to be strict in the array when necessary. Suppose array copying is implemented like this:

copy mv v = ... write mv i (v ! i) ...

For lazy arrays, v ! i would not be not be evaluated, which means that mv would unnecessarily retain a reference to v in each element written.

With indexM, copying can be implemented like this instead:

copy mv v = ... do
  x <- indexM v i
  write mv i x

Here, no references to v are retained because indexing (but not the elements) is evaluated eagerly.

Elementwise operations

Mapping

map :: (Contiguous arr1, Element arr1 b, Contiguous arr2, Element arr2 c) => (b -> c) -> arr1 b -> arr2 c

Map over the elements of an array.

Note that because a new array must be created, the resulting array type can be different than the original.

map' :: (Contiguous arr1, Element arr1 b, Contiguous arr2, Element arr2 c) => (b -> c) -> arr1 b -> arr2 c

Map strictly over the elements of an array.

Note that because a new array must be created, the resulting array type can be different than the original.

mapMutable :: (Contiguous arr, Element arr a, PrimMonad m) => (a -> a) -> Mutable arr (PrimState m) a -> m ()

Map over a mutable array, modifying the elements in place.

mapMutable' :: (PrimMonad m, Contiguous arr, Element arr a) => (a -> a) -> Mutable arr (PrimState m) a -> m ()

Strictly map over a mutable array, modifying the elements in place.

imap :: (Contiguous arr1, Element arr1 b, Contiguous arr2, Element arr2 c) => (Int -> b -> c) -> arr1 b -> arr2 c

Map over the elements of an array with the index.

imap' :: (Contiguous arr1, Element arr1 b, Contiguous arr2, Element arr2 c) => (Int -> b -> c) -> arr1 b -> arr2 c

Map strictly over the elements of an array with the index.

Note that because a new array must be created, the resulting array type can be different than the original.

Map over a mutable array with indices, modifying the elements in place.

imapMutable' :: (PrimMonad m, Contiguous arr, Element arr a) => (Int -> a -> a) -> Mutable arr (PrimState m) a -> m ()

Modify the elements of a mutable array in-place.

modify' :: (Contiguous arr, Element arr a, PrimMonad m) => (a -> a) -> Mutable arr (PrimState m) a -> m ()

Strictly modify the elements of a mutable array in-place.

mapMaybe :: forall arr1 arr2 a b. (Contiguous arr1, Element arr1 a, Contiguous arr2, Element arr2 b) => (a -> Maybe b) -> arr1 a -> arr2 b

The mapMaybe function is a version of map which can throw out elements. In particular, the functional arguments returns something of type Maybe b. If this is Nothing, no element is added on to the result array. If it is Just b, then b is included in the result array.

Zipping

zip :: (Contiguous arr1, Contiguous arr2, Contiguous arr3, Element arr1 a, Element arr2 b, Element arr3 (a, b)) => arr1 a -> arr2 b -> arr3 (a, b)

zip takes two arrays and returns an array of corresponding pairs.

zip [1, 2] ['a', 'b'] = [(1, 'a'), (2, 'b')]

If one input array is shorter than the other, excess elements of the longer array are discarded:

zip [1] ['a', 'b'] = [(1, 'a')]
zip [1, 2] ['a'] = [(1, 'a')]

zipWith :: (Contiguous arr1, Contiguous arr2, Contiguous arr3, Element arr1 a, Element arr2 b, Element arr3 c) => (a -> b -> c) -> arr1 a -> arr2 b -> arr3 c

zipWith generalises zip by zipping with the function given as the first argument, instead of a tupling function. For example, zipWith (+) is applied to two arrays to produce an array of the corresponding sums.

Specific elements

swap :: (Contiguous arr, Element arr a, PrimMonad m) => Mutable arr (PrimState m) a -> Int -> Int -> m ()

catMaybes :: (Contiguous arr, Element arr a, Element arr (Maybe a)) => arr (Maybe a) -> arr a

The catMaybes function takes a list of Maybes and returns a list of all the Just values.

lefts :: forall arr a b. (Contiguous arr, Element arr a, Element arr (Either a b)) => arr (Either a b) -> arr a

Extracts from an array of Either all the Left elements. All the Left elements are extracted in order.

rights :: forall arr a b. (Contiguous arr, Element arr b, Element arr (Either a b)) => arr (Either a b) -> arr b

Extracts from an array of Either all the Right elements. All the Right elements are extracted in order.

partitionEithers :: forall arr a b. (Contiguous arr, Element arr a, Element arr b, Element arr (Either a b)) => arr (Either a b) -> (arr a, arr b)

Partitions an array of Either into two arrays. All the Left elements are extracted, in order, to the first component of the output. Similarly the Right elements are extracted to the second component of the output.

Searching

find :: (Contiguous arr, Element arr a) => (a -> Bool) -> arr a -> Maybe a

find takes a predicate and an array, and returns the leftmost element of the array matching the prediate, or Nothing if there is no such predicate.

elem :: (Contiguous arr, Element arr a, Eq a) => a -> arr a -> Bool

Does the element occur in the structure?

maximum :: (Contiguous arr, Element arr a, Ord a) => arr a -> Maybe a

The largest element of a structure.

minimum :: (Contiguous arr, Element arr a, Ord a) => arr a -> Maybe a

The least element of a structure.

maximumBy :: (Contiguous arr, Element arr a) => (a -> a -> Ordering) -> arr a -> Maybe a

The largest element of a structure with respect to the given comparison function.

minimumBy :: (Contiguous arr, Element arr a) => (a -> a -> Ordering) -> arr a -> Maybe a

The least element of a structure with respect to the given comparison function.

Comparing for equality

equals :: (Contiguous arr, Element arr b, Eq b) => arr b -> arr b -> Bool

Test the two arrays for equality.

equalsMutable :: Contiguous arr => Mutable arr s a -> Mutable arr s a -> Bool

Test the two mutable arrays for pointer equality. Does not check equality of elements.

same :: Contiguous arr => arr a -> arr a -> Bool

This function does not behave deterministically. Optimization level and inlining can affect its results. However, the one thing that can be counted on is that if it returns True, the two immutable arrays are definitely the same. This is useful as shortcut for equality tests. However, keep in mind that a result of False tells us nothing about the arguments.

data PrimArray a

Arrays of unboxed elements. This accepts types like Double, Char, Int, and Word, as well as their fixed-length variants (Word8, Word16, etc.). Since the elements are unboxed, a PrimArray is strict in its elements. This differs from the behavior of Array, which is lazy in its elements.

data MutablePrimArray s a

Mutable primitive arrays associated with a primitive state token. These can be written to and read from in a monadic context that supports sequencing such as IO or ST. Typically, a mutable primitive array will be built and then convert to an immutable primitive array using unsafeFreezePrimArray. However, it is also acceptable to simply discard a mutable primitive array since it lives in managed memory and will be garbage collected when no longer referenced.
