Construction

Initialisation

new :: (PrimMonad m, MVector MVector (Rec Identity rs)) => Int -> m (MVector (PrimState m) (Rec Identity rs))

Create a mutable vector of the given length.

unsafeNew :: (PrimMonad m, MVector MVector (Rec Identity rs)) => Int -> m (MVector (PrimState m) (Rec Identity rs))

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

replicate :: (PrimMonad m, MVector MVector (Rec Identity rs)) => Int -> Rec Identity rs -> m (MVector (PrimState m) (Rec Identity rs))

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 MVector (Rec Identity rs)) => Int -> m (Rec Identity rs) -> m (MVector (PrimState m) (Rec Identity rs))

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 MVector (Rec Identity rs)) => MVector (PrimState m) (Rec Identity rs) -> m (MVector (PrimState m) (Rec Identity rs))

Create a copy of a mutable vector.

Growing

grow :: (PrimMonad m, MVector MVector (Rec Identity rs)) => MVector (PrimState m) (Rec Identity rs) -> Int -> m (MVector (PrimState m) (Rec Identity rs))

Grow a vector by the given number of elements. The number must be positive.

unsafeGrow :: (PrimMonad m, MVector MVector (Rec Identity rs)) => MVector (PrimState m) (Rec Identity rs) -> Int -> m (MVector (PrimState m) (Rec Identity rs))

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 MVector (Rec Identity rs)) => MVector (PrimState m) (Rec Identity rs) -> 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.

Accessing individual elements

read :: (PrimMonad m, MVector MVector (Rec Identity rs)) => MVector (PrimState m) (Rec Identity rs) -> Int -> m (Rec Identity rs)

Yield the element at the given position.

write :: (PrimMonad m, MVector MVector (Rec Identity rs)) => MVector (PrimState m) (Rec Identity rs) -> Int -> Rec Identity rs -> m ()

Replace the element at the given position.

swap :: (PrimMonad m, MVector MVector (Rec Identity rs)) => MVector (PrimState m) (Rec Identity rs) -> Int -> Int -> m ()

Swap the elements at the given positions.

unsafeRead :: (PrimMonad m, MVector MVector (Rec Identity rs)) => MVector (PrimState m) (Rec Identity rs) -> Int -> m (Rec Identity rs)

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

unsafeWrite :: (PrimMonad m, MVector MVector (Rec Identity rs)) => MVector (PrimState m) (Rec Identity rs) -> Int -> Rec Identity rs -> m ()

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

unsafeSwap :: (PrimMonad m, MVector MVector (Rec Identity rs)) => MVector (PrimState m) (Rec Identity rs) -> Int -> Int -> m ()

Swap the elements at the given positions. No bounds checks are performed.

Modifying vectors

Filling and copying

set :: (PrimMonad m, MVector MVector (Rec Identity rs)) => MVector (PrimState m) (Rec Identity rs) -> Rec Identity rs -> m ()

Set all elements of the vector to the given value.

copy :: (PrimMonad m, MVector MVector (Rec Identity rs)) => MVector (PrimState m) (Rec Identity rs) -> MVector (PrimState m) (Rec Identity rs) -> m ()

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

move :: (PrimMonad m, MVector MVector (Rec Identity rs)) => MVector (PrimState m) (Rec Identity rs) -> MVector (PrimState m) (Rec Identity rs) -> 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, MVector MVector (Rec Identity rs))

=> MVector (PrimState m) (Rec Identity rs)

target

-> MVector (PrimState m) (Rec Identity rs)

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, MVector MVector (Rec Identity rs))

=> MVector (PrimState m) (Rec Identity rs)

target

-> MVector (PrimState m) (Rec Identity rs)

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.
