# 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 -> a #

O(1) Indexing.

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

O(1) Safe indexing.

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

O(1) First element.

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

O(1) Last element.

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

O(1) Unsafe indexing without bounds checking.

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

O(1) First element, without checking if the vector is empty.

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

O(1) Last element, without checking if the vector is empty.

## Monadic indexing

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

O(1) Indexing in a monad.

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

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

For lazy vectors, `v ! i` would 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 element) is evaluated eagerly.

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

O(1) First element of a vector in a monad. See `indexM` for an explanation of why this is useful.

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

O(1) Last element of a vector in a monad. See `indexM` for an explanation of why this is useful.

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

O(1) Indexing in a monad, without bounds checks. See `indexM` for an explanation of why this is useful.

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

O(1) First element in a monad, without checking for empty vectors. See `indexM` for an explanation of why this is useful.

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

O(1) Last element in a monad, without checking for empty vectors. See `indexM` for an explanation of why this is useful.

## Extracting subvectors (slicing)

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.

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

O(1) Yield all but the last element without copying. The vector may not be empty.

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

## Enumeration

## 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.

# Utilities

## Comparisons

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

Checks whether two values are the same vector: they have same length and share the same buffer.

    >>> import qualified Data.Vector.Storable as VS
    >>> let xs = VS.fromList [0/0::Double] in VS.isSameVector xs xs
    True

# Conversions

## Lists

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

O(n) Convert a vector to a list.

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

O(n) Convert a list to a vector.

fromListN :: Storable a => Int -> [a] -> Vector a #

O(n) Convert the first `n` elements of a list to a vector. It's expected that the supplied list will be exactly `n` elements long. As an optimization, this function allocates a buffer for `n` elements, which could be used for DoS-attacks by exhausting the memory if an attacker controls that parameter.

    fromListN n xs = fromList (take n xs)

    >>> import qualified Data.Vector.Storable as VS

    >>> VS.fromListN 3 [1 :: Int]
    [1]

## Other vector types

convert :: (Vector v a, Vector w a) => v a -> w a #

O(n) Convert between different vector types.

unsafeCast :: forall a b. (Storable a, Storable b) => Vector a -> Vector b #

O(1) Unsafely cast a vector from one element type to another. This operation just changes the type of the underlying pointer and does not modify the elements.

The resulting vector contains as many elements as can fit into the underlying memory block.

unsafeCoerceVector :: Coercible a b => Vector a -> Vector b #

O(1) Unsafely coerce a mutable vector from one element type to another, representationally equal type. The operation just changes the type of the underlying pointer and does not modify the elements.

This is marginally safer than `unsafeCast`, since this function imposes an extra `Coercible` constraint. This function is still not safe, however, since it cannot guarantee that the two types have memory-compatible `Storable` instances.

## Mutable vectors

freeze :: (Storable a, PrimMonad m) => MVector (PrimState m) a -> m (Vector a) #

O(n) Yield an immutable copy of the mutable vector.

thaw :: (Storable a, PrimMonad m) => Vector a -> m (MVector (PrimState m) a) #

O(n) Yield a mutable copy of an immutable vector.

copy :: (Storable a, PrimMonad m) => MVector (PrimState m) a -> Vector a -> m () #

O(n) Copy an immutable vector into a mutable one. The two vectors must have the same length.

unsafeFreeze :: (Storable a, PrimMonad m) => MVector (PrimState m) a -> m (Vector a) #

O(1) Unsafely convert a mutable vector to an immutable one without copying. The mutable vector may not be used after this operation.

unsafeThaw :: (Storable a, PrimMonad m) => Vector a -> m (MVector (PrimState m) a) #

O(1) Unsafely convert an immutable vector to a mutable one without copying. Note that this is a very dangerous function and generally it's only safe to read from the resulting vector. In this case, the immutable vector could be used safely as well.

Problems with mutation happen because GHC has a lot of freedom to introduce sharing. As a result mutable vectors produced by `unsafeThaw` may or may not share the same underlying buffer. For example:

    foo = do
      let vec = V.generate 10 id
      mvec <- V.unsafeThaw vec
      do_something mvec

Here GHC could lift `vec` outside of foo which means that all calls to `do_something` will use same buffer with possibly disastrous results. Whether such aliasing happens or not depends on the program in question, optimization levels, and GHC flags.

All in all, attempts to modify a vector produced by `unsafeThaw` fall out of domain of software engineering and into realm of black magic, dark rituals, and unspeakable horrors. The only advice that could be given is: "Don't attempt to mutate a vector produced by `unsafeThaw` unless you know how to prevent GHC from aliasing buffers accidentally. We don't."

unsafeCopy :: (Storable a, PrimMonad m) => MVector (PrimState m) a -> Vector a -> m () #

O(n) Copy an immutable vector into a mutable one. The two vectors must have the same length. This is not checked.

# Raw pointers

unsafeFromForeignPtr #

Arguments

:: Storable a |
=> ForeignPtr a | pointer
-> Int | offset
-> Int | length
-> Vector a |

O(1) Create a vector from a `ForeignPtr` with an offset and a length.

The data may not be modified through the pointer afterwards.

If your offset is 0 it is more efficient to use `unsafeFromForeignPtr0`.

unsafeFromForeignPtr0 #

Arguments

:: ForeignPtr a | pointer
-> Int | length
-> Vector a |

O(1) Create a vector from a `ForeignPtr` and a length.

It is assumed the pointer points directly to the data (no offset). Use `unsafeFromForeignPtr` if you need to specify an offset.

The data may not be modified through the pointer afterwards.

unsafeToForeignPtr :: Vector a -> (ForeignPtr a, Int, Int) #

O(1) Yield the underlying `ForeignPtr` together with the offset to the data and its length. The data may not be modified through the `ForeignPtr`.

unsafeToForeignPtr0 :: Vector a -> (ForeignPtr a, Int) #

O(1) Yield the underlying `ForeignPtr` together with its length.

You can assume that the pointer points directly to the data (no offset).

The data may not be modified through the `ForeignPtr`.

unsafeWith :: Storable a => Vector a -> (Ptr a -> IO b) -> IO b #

Pass a pointer to the vector's data to the IO action. The data may not be modified through the 'Ptr.

# Re-exports
