# Accessors

## Length information

length :: Storable a => Vector a -> Int #

O(1) Yield the length of the vector.

null :: Storable a => Vector a -> Bool #

O(1) Test whether a vector is empty.

## Indexing

(!?) :: Storable a => Vector a -> Int -> Maybe a #

O(1) Safe indexing.

## Extracting subvectors

slice #

Arguments

:: Storable a |
=> Int | `i` starting index
-> Int | `n` length
-> Vector a |
-> Vector a |

O(1) Yield a slice of the vector without copying it. The vector must contain at least `i+n` elements.

take :: Storable a => Int -> Vector a -> Vector a #

O(1) Yield at the first `n` elements without copying. The vector may contain less than `n` elements, in which case it is returned unchanged.

drop :: Storable a => Int -> Vector a -> Vector a #

O(1) Yield all but the first `n` elements without copying. The vector may contain less than `n` elements, in which case an empty vector is returned.

splitAt :: Storable a => Int -> Vector a -> (Vector a, Vector a) #

O(1) Yield the first `n` elements paired with the remainder, without copying.

Note that ``splitAt` n v` is equivalent to `(`take` n v, `drop` n v)`, but slightly more efficient.

Since: vector-0.7.1

# Construction

## Initialisation

empty :: Storable a => Vector a #

O(1) The empty vector.

singleton :: Storable a => a -> Vector a #

O(1) A vector with exactly one element.

replicate :: Storable a => Int -> a -> Vector a #

O(n) A vector of the given length with the same value in each position.

generate :: Storable a => Int -> (Int -> a) -> Vector a #

O(n) Construct a vector of the given length by applying the function to each index.

iterateN :: Storable a => Int -> (a -> a) -> a -> Vector a #

O(n) Apply the function \(\max(n - 1, 0)\) times to an initial value, producing a vector of length \(\max(n, 0)\). The 0th element will contain the initial value, which is why there is one less function application than the number of elements in the produced vector.

\( \underbrace{x, f (x), f (f (x)), \ldots}_{\max(0,n)\rm{~elements}} \)

## Monadic initialisation

replicateM :: (Monad m, Storable a) => Int -> m a -> m (Vector a) #

O(n) Execute the monadic action the given number of times and store the results in a vector.

generateM :: (Monad m, Storable a) => Int -> (Int -> m a) -> m (Vector a) #

O(n) Construct a vector of the given length by applying the monadic action to each index.

iterateNM :: (Monad m, Storable a) => Int -> (a -> m a) -> a -> m (Vector a) #

O(n) Apply the monadic function \(\max(n - 1, 0)\) times to an initial value, producing a vector of length \(\max(n, 0)\). The 0th element will contain the initial value, which is why there is one less function application than the number of elements in the produced vector.

For a non-monadic version, see `iterateN`.

Since: vector-0.12.0.0

create :: Storable a => (forall s. ST s (MVector s a)) -> Vector a #

Execute the monadic action and freeze the resulting vector.

    create (do { v <- new 2; write v 0 'a'; write v 1 'b'; return v }) = <a,b>

createT :: (Traversable f, Storable a) => (forall s. ST s (f (MVector s a))) -> f (Vector a) #

Execute the monadic action and freeze the resulting vectors.

## Unfolding

unfoldr :: Storable a => (b -> Maybe (a, b)) -> b -> Vector a #

O(n) Construct a vector by repeatedly applying the generator function to a seed. The generator function yields `Just` the next element and the new seed or `Nothing` if there are no more elements.

    unfoldr (\n -> if n == 0 then Nothing else Just (n,n-1)) 10
     = <10,9,8,7,6,5,4,3,2,1>

unfoldrN :: Storable a => Int -> (b -> Maybe (a, b)) -> b -> Vector a #

O(n) Construct a vector with at most `n` elements by repeatedly applying the generator function to a seed. The generator function yields `Just` the next element and the new seed or `Nothing` if there are no more elements.

    unfoldrN 3 (\n -> Just (n,n-1)) 10 = <10,9,8>

unfoldrM :: (Monad m, Storable a) => (b -> m (Maybe (a, b))) -> b -> m (Vector a) #

## Enumeration

enumFromN :: (Storable a, Num a) => a -> Int -> Vector a #

O(n) Yield a vector of the given length, containing the values `x`, `x+1` etc. This operation is usually more efficient than `enumFromTo`.

    enumFromN 5 3 = <5,6,7>

enumFromStepN :: (Storable a, Num a) => a -> a -> Int -> Vector a #

O(n) Yield a vector of the given length, containing the values `x`, `x+y`, `x+y+y` etc. This operations is usually more efficient than `enumFromThenTo`.

    enumFromStepN 1 2 5 = <1,3,5,7,9>

enumFromTo :: (Storable a, Enum a) => a -> a -> Vector a #

O(n) Enumerate values from `x` to `y`.

WARNING: This operation can be very inefficient. If possible, use `enumFromN` instead.

enumFromThenTo :: (Storable a, Enum a) => a -> a -> a -> Vector a #

O(n) Enumerate values from `x` to `y` with a specific step `z`.

WARNING: This operation can be very inefficient. If possible, use `enumFromStepN` instead.

## Concatenation

cons :: Storable a => a -> Vector a -> Vector a #

O(n) Prepend an element.

snoc :: Storable a => Vector a -> a -> Vector a #

O(n) Append an element.

(++) :: Storable a => Vector a -> Vector a -> Vector a infixr 5 #

O(m+n) Concatenate two vectors.

concat :: Storable a => [Vector a] -> Vector a #

O(n) Concatenate all vectors in the list.

## Restricting memory usage

force :: Storable a => Vector a -> Vector a #

O(n) Yield the argument, but force it not to retain any extra memory, possibly by copying it.

This is especially useful when dealing with slices. For example:

    force (slice 0 2 <huge vector>)

Here, the slice retains a reference to the huge vector. Forcing it creates a copy of just the elements that belong to the slice and allows the huge vector to be garbage collected.

# Modifying vectors

## Permutations

reverse :: Storable a => Vector a -> Vector a #

O(n) Reverse a vector.

## Safe destructive update

modify :: Storable a => (forall s. MVector s a -> ST s ()) -> Vector a -> Vector a #

Apply a destructive operation to a vector. The operation may be performed in place if it is safe to do so and will modify a copy of the vector otherwise (see `New` for details).
