# Accessors

## Length information

## Extracting subvectors

slice :: Unbox a => Int -> Int -> MVector s a -> MVector 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.

unsafeInit :: Unbox a => MVector s a -> MVector s aSource

unsafeTail :: Unbox a => MVector s a -> MVector s aSource

## Overlapping

# 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.

# 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.

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
copied to a temporary vector and then the temporary vector was copied
to the target vector.
