Construction

Initialisation

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

Create a mutable vector of the given length.

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

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

replicate :: (PrimMonad m, Unbox a) => Int -> a -> m (MVector (PrimState m) a) #

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) #

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) #

Create a copy of a mutable vector.

Growing

grow :: (PrimMonad m, Unbox a) => MVector (PrimState m) a -> Int -> m (MVector (PrimState m) a) #

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) #

Restricting memory usage

clear :: (PrimMonad m, Unbox a) => MVector (PrimState m) a -> m () #

Reset all elements of the vector to some undefined value, clearing all references to external objects. This is usually a noop for unboxed vectors.

Swap the elements at the given positions.

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

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

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

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

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

Modifying vectors

nextPermutation :: (PrimMonad m, Ord e, Unbox e) => MVector (PrimState m) e -> m Bool #

Filling and copying

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

Set all elements of the vector to the given value.

copy #

Arguments

:: (PrimMonad m, Unbox 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 :: (PrimMonad m, Unbox a) => MVector (PrimState m) a -> MVector (PrimState m) a -> 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 #

Arguments

:: (PrimMonad m, Unbox 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 #

Arguments

:: (PrimMonad m, Unbox 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.
