class Storable a #

The member functions of this class facilitate writing values of primitive types to raw memory (which may have been allocated with the above mentioned routines) and reading values from blocks of raw memory. The class, furthermore, includes support for computing the storage requirements and alignment restrictions of storable types.

Memory addresses are represented as values of type ``Ptr` a`, for some `a` which is an instance of class `Storable`. The type argument to `Ptr` helps provide some valuable type safety in FFI code (you can't mix pointers of different types without an explicit cast), while helping the Haskell type system figure out which marshalling method is needed for a given pointer.

All marshalling between Haskell and a foreign language ultimately boils down to translating Haskell data structures into the binary representation of a corresponding data structure of the foreign language and vice versa. To code this marshalling in Haskell, it is necessary to manipulate primitive data types stored in unstructured memory blocks. The class `Storable` facilitates this manipulation on all types for which it is instantiated, which are the standard basic types of Haskell, the fixed size `Int` types (`Int8`, `Int16`, `Int32`, `Int64`), the fixed size `Word` types (`Word8`, `Word16`, `Word32`, `Word64`), `StablePtr`, all types from Foreign.C.Types, as well as `Ptr`.

# 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 elements) 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 #

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

     = <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.

## 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`.

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

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

## 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.

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

# 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

    fromListN n xs = fromList (take n xs)

## Other vector types

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

O(n) Convert 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. The 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.

## 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 the 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) Unsafe 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. The immutable vector may not be used after this operation.

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 `ForeignPtr` afterwards.

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

unsafeFromForeignPtr0 #

Arguments

:: Storable a |
=> 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 `ForeignPtr` afterwards.

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

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

You can assume 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.
