# Class of mutable vector types

class MVector v a where Source

Class of mutable vectors parametrised with a primitive state token.

Minimum complete implementation:

basicLength :: v s a -> Int Source

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

instead.

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 -> Bool Source

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 a Source

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

Set all elements of the vector to the given value. This method should
not be called directly, use `set`

instead.

Copy a vector. The two vectors may not overlap. This method should not
be called directly, use `unsafeCopy`

instead.

Move the contents of a vector. The two vectors may overlap. This method
should not be called directly, use `unsafeMove`

instead.

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

Grow a vector by the given number of elements. This method should not be
called directly, use `unsafeGrow`

instead.

# Accessors

## Length information

## Extracting subvectors

slice :: MVector v a => Int -> Int -> v s a -> v s a Source

Yield a part of the mutable vector without copying it.

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

unsafeInit :: MVector v a => v s a -> v s a Source

unsafeTail :: MVector v a => v s a -> v s a Source

## Overlapping

# 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

# Modifying vectors

## Filling and copying

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

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

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.

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

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
