Synopsis

Class of mutable vector types

class MVector v a whereSource

Class of mutable vectors parametrised with a primitive state token.

Minimum complete implementation:

Methods

basicLength :: v s a -> IntSource

Length of the mutable vector. This method should not be called directly, use length instead.

basicUnsafeSliceSource

Arguments

:: Int

starting index

-> Int

length of the slice

-> v s a 
-> v s a 

Yield a part of the mutable vector without copying it. This method should not be called directly, use unsafeSlice instead.

basicOverlaps :: v s a -> v s a -> BoolSource

basicUnsafeNew :: PrimMonad m => Int -> m (v (PrimState m) a)Source

Create a mutable vector of the given length. This method should not be called directly, use unsafeNew instead.

basicUnsafeReplicate :: PrimMonad m => Int -> a -> m (v (PrimState m) a)Source

Create a mutable vector of the given length and fill it with an initial value. This method should not be called directly, use replicate instead.

basicUnsafeRead :: PrimMonad m => v (PrimState m) a -> Int -> m aSource

Yield the element at the given position. This method should not be called directly, use unsafeRead instead.

basicUnsafeWrite :: PrimMonad m => v (PrimState m) a -> Int -> a -> m ()Source

Replace the element at the given position. This method should not be called directly, use unsafeWrite instead.

basicClear :: PrimMonad m => v (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. This method should not be called directly, use clear instead.

basicSet :: PrimMonad m => v (PrimState m) a -> a -> m ()Source

basicUnsafeCopySource

Arguments

:: PrimMonad m

target

-> v (PrimState m) a

source

Arguments

:: PrimMonad m 
=> v (PrimState m) a

target

-> v (PrimState m) a

source

-> m ()

Construction

Initialisation

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

Create a mutable vector of the given length.

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

Create a mutable vector of the given length. The length is not checked.

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

Create a copy of a mutable vector.

Growing

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

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

unsafeGrow :: (PrimMonad m, MVector v a) => v (PrimState m) a -> Int -> m (v (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, MVector v a) => v (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.

Accessing individual elements

read :: (PrimMonad m, MVector v a) => v (PrimState m) a -> Int -> m aSource

Yield the element at the given position.

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

Replace the element at the given position.

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

Swap the elements at the given positions.

unsafeRead :: (PrimMonad m, MVector v a) => v (PrimState m) a -> Int -> m aSource

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

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

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

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

Swap the elements at the given positions. No bounds checks are performed.

Modifying vectors

Filling and copying

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

Set all elements of the vector to the given value.

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

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

move :: (PrimMonad m, MVector v a) => v (PrimState m) a -> v (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.

unsafeCopySource

Arguments

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

target

-> v (PrimState m) a

source

-> m () 

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

unsafeMoveSource

Arguments

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

target

-> v (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.
