Description

Generic interface to mutable vectors

Synopsis

Class of mutable vector types

class MVector v a where Source #

Class of mutable vectors parametrised with a primitive state token.

Methods

basicLength :: v s a -> Int Source #

Length of the mutable vector. This method should not be called directly, use length instead.

basicUnsafeSlice Source #

Arguments

:: Int

starting index

-> Int

length of the slice

-> v s a 
-> v s a 

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 #

Check whether two vectors overlap. This method should not be called directly, use overlaps instead.

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.

basicInitialize :: PrimMonad m => v (PrimState m) a -> m () Source #

Initialize a vector to a standard value. This is intended to be called as part of the safe new operation (and similar operations), to properly blank the newly allocated memory if necessary.

Vectors that are necessarily initialized as part of creation may implement this as a no-op.

Since: 0.11.0.0

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.

basicUnsafeCopy Source #

Arguments

:: PrimMonad m 
=> v (PrimState m) a

target

-> v (PrimState m) a

source

-> m () 

Copy a vector. The two vectors may not overlap. This method should not be called directly, use unsafeCopy instead.

basicUnsafeMove Source #

Arguments

:: PrimMonad m 
=> v (PrimState m) a

target

-> v (PrimState m) a

source

-> m () 

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.

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

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.

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.

growFront :: (PrimMonad m, MVector v a) => v (PrimState m) a -> Int -> m (v (PrimState m) a) Source #

unsafeGrowFront :: (PrimMonad m, MVector v a) => v (PrimState m) a -> Int -> m (v (PrimState m) a) Source #

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

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

Yield the element at the given position.

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

Replace the element at the given position.

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

Modify the element at the given position.

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

Swap the elements at the given positions.

exchange :: (PrimMonad m, MVector v a) => v (PrimState m) a -> Int -> a -> m a Source #

Replace the element at the given position and return the old element.

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 #

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

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

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

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

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

unsafeExchange :: (PrimMonad m, MVector v a) => v (PrimState m) a -> Int -> a -> m a Source #

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

Modifying vectors

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

Compute the next (lexicographically) permutation of given vector in-place. Returns False when input is the last permutation

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 Source #

Arguments

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

target

-> v (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, MVector v a) 
=> v (PrimState m) a

target

-> v (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, MVector v a) 
=> v (PrimState m) a

target

-> v (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, MVector v a) 
=> v (PrimState m) a

target

-> v (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.

mstreamR :: (PrimMonad m, MVector v a) => v (PrimState m) a -> Stream m a Source #

unstream :: (PrimMonad m, MVector v a) => Bundle u a -> m (v (PrimState m) a) Source #

Create a new mutable vector and fill it with elements from the Bundle. The vector will grow exponentially if the maximum size of the Bundle is unknown.

unstreamR :: (PrimMonad m, MVector v a) => Bundle u a -> m (v (PrimState m) a) Source #

Create a new mutable vector and fill it with elements from the Bundle from right to left. The vector will grow exponentially if the maximum size of the Bundle is unknown.

vunstream :: (PrimMonad m, Vector v a) => Bundle v a -> m (Mutable v (PrimState m) a) Source #

munstream :: (PrimMonad m, MVector v a) => MBundle m u a -> m (v (PrimState m) a) Source #

Create a new mutable vector and fill it with elements from the monadic stream. The vector will grow exponentially if the maximum size of the stream is unknown.

munstreamR :: (PrimMonad m, MVector v a) => MBundle m u a -> m (v (PrimState m) a) Source #
