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.

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.

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

Yield the element at the given position.
write :: (PrimMonad m, MVector v a) => v (PrimState m) a -> Int -> a -> m () Source

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 a Source
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

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

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.
