Accessors

Length information

length :: Unbox a => MVector s a -> Int Source #

Length of the mutable vector.

null :: Unbox a => MVector s a -> Bool Source #

Check whether the vector is empty

Extracting subvectors

slice Source #

Arguments

:: Unbox 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 :: Unbox a => MVector s a -> MVector s a Source #

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

tail :: Unbox a => MVector s a -> MVector s a Source #

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

take :: Unbox a => Int -> MVector s a -> MVector s a Source #

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

drop :: Unbox a => Int -> MVector s a -> MVector s a Source #

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

unsafeSlice Source #

Arguments

:: Unbox 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 :: Unbox a => MVector s a -> MVector s a Source #

Same as init but doesn't do range checks.

unsafeTail :: Unbox a => MVector s a -> MVector s a Source #

Same as tail but doesn't do range checks.

unsafeTake :: Unbox a => Int -> MVector s a -> MVector s a Source #

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

unsafeDrop :: Unbox a => Int -> MVector s a -> MVector s a Source #

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

Overlapping

overlaps :: Unbox a => MVector s a -> MVector s a -> Bool Source #

Check whether two vectors overlap.

Construction

Initialisation

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

Create a mutable vector of the given length.

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

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

Since: 0.5

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

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

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

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, Unbox a) => Int -> ( Int -> a) -> m ( MVector ( PrimState m) a) Source #

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.

Since: 0.12.3.0

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

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

Create a copy of a mutable vector.

Growing

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

Grow an unboxed vector by the given number of elements. The number must be non-negative. Same semantics as in grow for generic vector.

Examples

Expand
>>> import qualified Data.Vector.Unboxed as VU
>>> import qualified Data.Vector.Unboxed.Mutable as MVU
>>> mv <- VU.thaw $ VU.fromList ([('a', 10), ('b', 20), ('c', 30)] :: [(Char, Int)])
>>> mv' <- MVU.grow mv 2

Extra memory at the end of the newly allocated vector is initialized to 0 bytes, which for Unbox instance will usually correspond to some default value for a particular type, eg. 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:

>>> VU.freeze mv'
[('a',10),('b',20),('c',30),('\NUL',0),('\NUL',0)]

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

>>> MVU.write mv' 3 ('d', 999)
>>> VU.freeze mv'
[('a',10),('b',20),('c',30),('d',999),('\NUL',0)]

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

>>> MVU.write mv' 2 ('X', 888)
>>> VU.freeze mv'
[('a',10),('b',20),('X',888),('d',999),('\NUL',0)]
>>> VU.freeze mv
[('a',10),('b',20),('c',30)]

Since: 0.5

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

Grow a vector by the given number of elements. The number must be non-negative but this is not checked. Same semantics as in unsafeGrow for generic vector.

Since: 0.5

Restricting memory usage

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

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

Zipping and unzipping

zip :: ( Unbox a, Unbox b) => MVector s a -> MVector s b -> MVector s (a, b) Source #

O(1) Zip 2 vectors

Modifying vectors

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

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

Filling and copying

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

Set all elements of the vector to the given value.

copy Source #

Arguments

:: ( PrimMonad m, Unbox 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 Source #

Arguments

:: ( PrimMonad m, Unbox 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 Source #

Arguments

:: ( PrimMonad m, Unbox 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. This is not checked.

unsafeMove Source #

Arguments

:: ( PrimMonad m, Unbox 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.
