Data.Vector.Unboxed

Description

Adaptive unboxed vectors. The implementation is based on type families and picks an efficient, specialised representation for every element type. For example, unboxed vectors of pairs are represented as pairs of unboxed vectors.

Implementing unboxed vectors for new data types can be very easy. Here is how the library does this for Complex by simply wrapping vectors of pairs.

newtype instance MVector s (Complex a) = MV_Complex (MVector s (a,a))
newtype instance Vector    (Complex a) = V_Complex  (Vector    (a,a))

instance (RealFloat a, Unbox a) => MVector MVector (Complex a) where
  {-# INLINE basicLength #-}
  basicLength (MV_Complex v) = basicLength v
  ...

instance (RealFloat a, Unbox a) => Data.Vector.Generic.Vector Vector (Complex a) where
  {-# INLINE basicLength #-}
  basicLength (V_Complex v) = Data.Vector.Generic.basicLength v
  ...

instance (RealFloat a, Unbox a) => Unbox (Complex a)

For newtypes, defining instances is easier since one could use GeneralizedNewtypeDeriving in order to derive instances for Vector and MVector, since they're very cumbersome to write by hand:

>>> :set -XTypeFamilies -XStandaloneDeriving -XMultiParamTypeClasses -XGeneralizedNewtypeDeriving
>>> 
>>> import qualified Data.Vector.Unboxed         as U
>>> import qualified Data.Vector.Generic         as G
>>> import qualified Data.Vector.Generic.Mutable as M
>>> 
>>> newtype Foo = Foo Int
>>> 
>>> newtype instance U.MVector s Foo = MV_Int (U.MVector s Int)
>>> newtype instance U.Vector    Foo = V_Int  (U.Vector    Int)
>>> deriving instance M.MVector MVector Foo
>>> deriving instance G.Vector  Vector  Foo
>>> instance Unbox Foo

Accessors

Length information

length :: Unbox a => Vector a -> Int Source #

O(1) Yield the length of the vector.

null :: Unbox a => Vector a -> Bool Source #

O(1) Test whether a vector is empty.

Indexing

(!) :: Unbox a => Vector a -> Int -> a Source #

O(1) Indexing.

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

O(1) Safe indexing.

head :: Unbox a => Vector a -> a Source #

O(1) First element.

last :: Unbox a => Vector a -> a Source #

O(1) Last element.

unsafeIndex :: Unbox a => Vector a -> Int -> a Source #

O(1) Unsafe indexing without bounds checking.

unsafeHead :: Unbox a => Vector a -> a Source #

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

unsafeLast :: Unbox a => Vector a -> a Source #

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

Monadic indexing

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

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 :: (Unbox a, Monad m) => Vector a -> m a Source #

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

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

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

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

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

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

Construction

Initialisation

Enumeration

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

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

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

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.

Restricting memory usage

force :: Unbox a => Vector a -> Vector a Source #

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.

fromListN :: Unbox a => Int -> [a] -> Vector a Source #

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

Other vector types

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

O(n) Convert between different vector types.

Mutable vectors

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

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

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

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

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

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

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

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

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

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 :: (Unbox a, PrimMonad m) => MVector (PrimState m) a -> Vector a -> m () Source #

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

Deriving via

newtype UnboxViaPrim a Source #

Newtype wrapper which allows to derive unboxed vector in term of primitive vectors using DerivingVia mechanism. This is mostly used as illustration of use of DerivingVia for vector, see examples below.

First is rather straightforward: we define newtype and use GND to derive Prim instance. Newtype instances should be defined manually. Then we use deriving via to define necessary instances.

>>> :set -XTypeFamilies -XStandaloneDeriving -XDerivingVia -XMultiParamTypeClasses
>>> -- Needed to derive Prim
>>> :set -XGeneralizedNewtypeDeriving -XDataKinds -XUnboxedTuples -XPolyKinds
>>> 
>>> import qualified Data.Vector.Unboxed         as U
>>> import qualified Data.Vector.Primitive       as P
>>> import qualified Data.Vector.Generic         as G
>>> import qualified Data.Vector.Generic.Mutable as M
>>> 
>>> newtype Foo = Foo Int deriving P.Prim
>>> 
>>> newtype instance U.MVector s Foo = MV_Int (P.MVector s Foo)
>>> newtype instance U.Vector    Foo = V_Int  (P.Vector    Foo)
>>> deriving via (U.UnboxViaPrim Foo) instance M.MVector MVector Foo
>>> deriving via (U.UnboxViaPrim Foo) instance G.Vector  Vector  Foo
>>> instance Unbox Foo

Second example is essentially same but with a twist. Instead of using Prim instance of data type, we use underlying instance of Int:

>>> :set -XTypeFamilies -XStandaloneDeriving -XDerivingVia -XMultiParamTypeClasses
>>> 
>>> import qualified Data.Vector.Unboxed         as U
>>> import qualified Data.Vector.Primitive       as P
>>> import qualified Data.Vector.Generic         as G
