# Class of mutable vector types

Class of mutable vectors parametrised with a primitive state token.

basicLength :: v s a -> IntSource

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 -> 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

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.

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.

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

*DEPRECATED* in favour of `basicUnsafeReplicate`

# Accessors

## Length information

## Extracting subvectors

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

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.

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.
