Construction

Initialisation

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

Create a mutable vector of the given length.

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

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

replicate :: (PrimMonad m, Storable 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, Storable 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, Storable a) => MVector (PrimState m) a -> m (MVector (PrimState m) a) Source #

Create a copy of a mutable vector.

Growing

grow :: (PrimMonad m, Storable 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, Storable 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, Storable 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.

Accessing individual elements

read :: (PrimMonad m, Storable a) => MVector (PrimState m) a -> Int -> m a Source #

Yield the element at the given position.

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

Replace the element at the given position.

modify :: (PrimMonad m, Storable a) => MVector (PrimState m) a -> (a -> a) -> Int -> m () Source #

Modify the element at the given position.

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

Swap the elements at the given positions.

unsafeRead :: (PrimMonad m, Storable a) => MVector (PrimState m) a -> Int -> m a Source #

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

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

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

unsafeModify :: (PrimMonad m, Storable a) => MVector (PrimState m) a -> (a -> a) -> Int -> m () Source #

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

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

Modifying vectors

Filling and copying

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

Set all elements of the vector to the given value.

copy Source #

Arguments

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

target

-> MVector (PrimState m) a

source

-> m () 

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

move Source #

Arguments

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

target

-> MVector (PrimState m) a

source

-> m () 

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.

unsafeCopy Source #

Arguments

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

target

-> MVector (PrimState m) a

source

-> m () 

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

unsafeMove Source #

Arguments

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

target

-> MVector (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.

Unsafe conversions

unsafeCast :: forall a b s. (Storable a, Storable b) => MVector s a -> MVector s b Source #

O(1) Unsafely cast a mutable vector from one element type to another. The operation just changes the type of the underlying pointer and does not modify the elements.

The resulting vector contains as many elements as can fit into the underlying memory block.

Raw pointers

unsafeFromForeignPtr Source #

Arguments

:: Storable a 
=> ForeignPtr a

pointer

-> Int

offset

-> Int

length

-> MVector s a 

Create a mutable vector from a ForeignPtr with an offset and a length.

Modifying data through the ForeignPtr afterwards is unsafe if the vector could have been frozen before the modification.

If your offset is 0 it is more efficient to use unsafeFromForeignPtr0.

unsafeFromForeignPtr0 Source #

Arguments

:: Storable a 
=> ForeignPtr a

pointer

-> Int

length

-> MVector s a 

O(1) Create a mutable vector from a ForeignPtr and a length.

It is assumed the pointer points directly to the data (no offset). Use unsafeFromForeignPtr if you need to specify an offset.

Modifying data through the ForeignPtr afterwards is unsafe if the vector could have been frozen before the modification.

unsafeToForeignPtr :: Storable a => MVector s a -> (ForeignPtr a, Int, Int) Source #

Yield the underlying ForeignPtr together with the offset to the data and its length. Modifying the data through the ForeignPtr is unsafe if the vector could have frozen before the modification.

unsafeToForeignPtr0 :: Storable a => MVector s a -> (ForeignPtr a, Int) Source #

O(1) Yield the underlying ForeignPtr together with its length.

You can assume the pointer points directly to the data (no offset).

Modifying the data through the ForeignPtr is unsafe if the vector could have frozen before the modification.

unsafeWith :: Storable a => IOVector a -> (Ptr a -> IO b) -> IO b Source #

Pass a pointer to the vector's data to the IO action. Modifying data through the pointer is unsafe if the vector could have been frozen before the modification.
