Accessors

Length information

length :: Storable a => MVector s a -> Int #

Length of the mutable vector.

null :: Storable a => MVector s a -> Bool #

Check whether the vector is empty.

Extracting subvectors

slice #

Arguments

:: Storable a 
=> Int

i starting index

-> Int

n length

-> MVector s a 
-> MVector s a 

Yield a part of the mutable vector without copying it. The vector must contain at least i+n elements.

init :: Storable a => MVector s a -> MVector s a #

Drop the last element of the mutable vector without making a copy. If the vector is empty, an exception is thrown.

tail :: Storable a => MVector s a -> MVector s a #

Drop the first element of the mutable vector without making a copy. If the vector is empty, an exception is thrown.

take :: Storable a => Int -> MVector s a -> MVector s a #

Take the n first elements of the mutable vector without making a copy. For negative n, the empty vector is returned. If n is larger than the vector's length, the vector is returned unchanged.

drop :: Storable a => Int -> MVector s a -> MVector s a #

Drop the n first element of the mutable vector without making a copy. For negative n, the vector is returned unchanged. If n is larger than the vector's length, the empty vector is returned.

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

O(1) Split the mutable vector into the first n elements and the remainder, without copying.

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

unsafeSlice #

Arguments

:: Storable a 
=> Int

starting index

-> Int

length of the slice

-> MVector s a 
-> MVector s a 

Yield a part of the mutable vector without copying it. No bounds checks are performed.

unsafeInit :: Storable a => MVector s a -> MVector s a #

Same as init, but doesn't do range checks.

unsafeTail :: Storable a => MVector s a -> MVector s a #

Same as tail, but doesn't do range checks.

unsafeTake :: Storable a => Int -> MVector s a -> MVector s a #

Unsafe variant of take. If n is out of range, it will simply create an invalid slice that likely violate memory safety.

unsafeDrop :: Storable a => Int -> MVector s a -> MVector s a #

Unsafe variant of drop. If n is out of range, it will simply create an invalid slice that likely violate memory safety.

Overlapping

overlaps :: Storable a => MVector s a -> MVector s a -> Bool #

Check whether two vectors overlap.

Construction

Initialisation

new :: (PrimMonad m, Storable a) => Int -> m (MVector (PrimState m) a) #

Create a mutable vector of the given length.

unsafeNew :: (PrimMonad m, Storable a) => Int -> m (MVector (PrimState m) a) #

Create a mutable vector of the given length. The vector content is uninitialized, which means it is filled with whatever the underlying memory buffer happens to contain.

Since: 0.5

replicate :: (PrimMonad m, Storable a) => Int -> a -> m (MVector (PrimState m) a) #

Create a mutable vector of the given length (0 if the length is negative) and fill it with an initial value.

replicateM :: (PrimMonad m, Storable a) => Int -> m a -> m (MVector (PrimState m) a) #

Create a mutable vector of the given length (0 if the length is negative) and fill it with values produced by repeatedly executing the monadic action.

generate :: (PrimMonad m, Storable a) => Int -> (Int -> a) -> m (MVector (PrimState m) a) #

O(n) Create a mutable vector of the given length (0 if the length is negative) and fill it with the results of applying the function to each index. Iteration starts at index 0.

Since: 0.12.3.0

generateM :: (PrimMonad m, Storable a) => Int -> (Int -> m a) -> m (MVector (PrimState m) a) #

O(n) Create a mutable vector of the given length (0 if the length is negative) and fill it with the results of applying the monadic function to each index. Iteration starts at index 0.

Since: 0.12.3.0

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

Create a copy of a mutable vector.

Growing

grow :: (PrimMonad m, Storable a) => MVector (PrimState m) a -> Int -> m (MVector (PrimState m) a) #

Grow a storable vector by the given number of elements. The number must be non-negative. This has the same semantics as grow for generic vectors.

Examples

Expand
>>> import qualified Data.Vector.Storable as VS
>>> import qualified Data.Vector.Storable.Mutable as MVS
>>> mv <- VS.thaw $ VS.fromList ([10, 20, 30] :: [Int])
>>> mv' <- MVS.grow mv 2

Extra memory at the end of the newly allocated vector is initialized to 0 bytes, which for Storable instances will usually correspond to some default value for a particular type, e.g. 0 for Int, False for Bool, etc. However, if unsafeGrow was used instead, this would not have been guaranteed and some garbage would be there instead.

>>> VS.freeze mv'
[10,20,30,0,0]

Having the extra space we can write new values in there:

>>> MVS.write mv' 3 999
>>> VS.freeze mv'
[10,20,30,999,0]

It is important to note that the source mutable vector is not affected when the newly allocated one is mutated.

>>> MVS.write mv' 2 888
>>> VS.freeze mv'
[10,20,888,999,0]
>>> VS.freeze mv
[10,20,30]

Since: 0.5

unsafeGrow :: (PrimMonad m, Storable a) => MVector (PrimState m) a -> Int -> m (MVector (PrimState m) a) #

Grow a vector by the given number of elements. The number must be non-negative, but this is not checked. This has the same semantics as unsafeGrow for generic vectors.

Since: 0.5

Restricting memory usage

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

Reset all elements of the vector to some undefined value, clearing all references to external objects. This is a noop.

Accessing individual elements

read :: (PrimMonad m, Storable a) => MVector (PrimState m) a -> Int -> m a #

Yield the element at the given position. Will throw an exception if the index is out of range.

Examples

Expand
>>> import qualified Data.Vector.Storable.Mutable as MVS
>>> v <- MVS.generate 10 (\x -> x*x)
>>> MVS.read v 3
9

readMaybe :: (PrimMonad m, Storable a) => MVector (PrimState m) a -> Int -> m (Maybe a) #

Yield the element at the given position. Returns Nothing if the index is out of range.

Examples

Expand
>>> import qualified Data.Vector.Storable.Mutable as MVS
>>> v <- MVS.generate 10 (\x -> x*x)
>>> MVS.readMaybe v 3
Just 9
>>> MVS.readMaybe v 13
Nothing

Modifying vectors

nextPermutation :: (PrimMonad m, Storable e, Ord e) => MVector (PrimState m) e -> m Bool #

Compute the (lexicographically) next permutation of the given vector in-place. Returns False when the input is the last permutation.

Filling and copying

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

Set all elements of the vector to the given value.

copy #

Arguments

:: (PrimMonad m, Storable a) 
=> MVector (PrimState m) a

target

-> MVector (PrimState m) a

source

-> m () 

Copy a vector. The two vectors must have the same length and may not overlap.

move #

Arguments

:: (PrimMonad m, Storable a) 
=> MVector (PrimState m) a

target

-> MVector (PrimState m) a

source

-> m () 

Move the contents of a vector. The two vectors must have the same length.

If the vectors do not overlap, then this is equivalent to copy. Otherwise, the copying is performed as if the source vector were copied to a temporary vector and then the temporary vector was copied to the target vector.

unsafeCopy #

Arguments

:: (PrimMonad m, Storable a) 
=> MVector (PrimState m) a

target

-> MVector (PrimState m) a

source

-> m () 

Copy a vector. The two vectors must have the same length and may not overlap, but this is not checked.

unsafeMove #

Arguments

:: (PrimMonad m, Storable a) 
=> MVector (PrimState m) a

target

-> MVector (PrimState m) a

source

-> m () 

Move the contents of a vector. The two vectors must have the same length, but this is not checked.

If the vectors do not overlap, then this is equivalent to unsafeCopy. Otherwise, the copying is performed as if the source vector were copied to a temporary vector and then the temporary vector was copied to the target vector.

Unsafe conversions

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

O(1) Unsafely cast a mutable 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.

unsafeCoerceMVector :: Coercible a b => MVector s a -> MVector s 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.

Raw pointers

unsafeFromForeignPtr #

Arguments

:: Storable a 
=> ForeignPtr a

pointer

-> Int

offset

-> Int

length

-> MVector s a 

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

Modifying data through the ForeignPtr afterwards is unsafe if the vector could have been frozen before the modification.

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

unsafeFromForeignPtr0 #

Arguments

:: ForeignPtr a

pointer

-> Int

length

-> MVector s a 

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

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

Modifying data through the ForeignPtr afterwards is unsafe if the vector could have been frozen before the modification.

unsafeToForeignPtr :: MVector s a -> (ForeignPtr a, Int, Int) #

O(1) Yield the underlying ForeignPtr together with the offset to the data and its length. Modifying the data through the ForeignPtr is unsafe if the vector could have been frozen before the modification.

unsafeToForeignPtr0 :: MVector s 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).

Modifying the data through the ForeignPtr is unsafe if the vector could have been frozen before the modification.

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

Pass a pointer to the vector's data to the IO action. Modifying data through the pointer is unsafe if the vector could have been frozen before the modification.
