unsafeSlice Source

Arguments

:: Unbox a

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

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 length is not checked.

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.

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 a vector by the given number of elements. The number must be positive.

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 positive but this is not checked.

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

O(1) Zip 6 vectors

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

O(1) Unzip 2 vectors

unzip3 :: (Unbox a, Unbox b, Unbox c) => MVector s (a, b, c) -> (MVector s a, MVector s b, MVector s c) Source

unzip6 :: (Unbox a, Unbox b, Unbox c, Unbox d, Unbox e, Unbox f) => MVector s (a, b, c, d, e, f) -> (MVector s a, MVector s b, MVector s c, MVector s d, MVector s e, MVector s f) Source

O(1) Unzip 6 vectors

Accessing individual elements

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

Yield the element at the given position.

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

Replace the element at the given position.

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

Modify the element at the given position.

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

Swap the elements at the given positions.

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

Yield the element at the given position. No bounds checks are performed.

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

Replace the element at the given position. No bounds checks are performed.

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

Modify the element at the given position. No bounds checks are performed.

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

Modifying vectors

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

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

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

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.
