Z.Data.Vector.Base

Description

This module provides unified vector interface. Conceptually a vector is simply a slice of an array, for example this is the definition of boxed vector:

data Vector a = Vector !(SmallArray a)   !Int    !Int
                     -- payload           offset  length

The Vec class unified different type of vectors, and this module provide operation over Vec instances, with all the internal structures. Be careful on modifying internal slices, otherwise segmentation fault await.

Synopsis

The Vec typeclass

class Arr (IArray v) a => Vec v a where Source #

Typeclass for box and unboxed vectors, which are created by slicing arrays.

Instead of providing a generalized vector with polymorphric array field, we use this typeclass so that instances use concrete array type can unpack their array payload.

Vector types, e.g. Vector,PrimVector... are obivious instances, with O(1) toArr and fromArr, which convert slices to (array, offset, length) tuple back and forth.

Array types can also be instances of this class, e.g. Array, PrimArray..., in this case toArr will always return offset 0 and whole array length, and fromArr is O(n) copyArr.

Associated Types

unpackR :: Vec v a => v a -> [a] Source #

O(n) Convert vector to a list in reverse order.

This function is a good producer in the sense of build/foldr fusion.

Basic interface

null :: Vec v a => v a -> Bool Source #

length :: Vec v a => v a -> Int Source #

O(1) The length of a vector.

append :: Vec v a => v a -> v a -> v a Source #

O(m+n)

There's no need to guard empty vector because we guard them for you, so appending empty vectors are no-ops.

map :: forall u v a b. (Vec u a, Vec v b) => (a -> b) -> u a -> v b Source #

Mapping between vectors (possiblely with two different vector types).

NOTE, the result vector contain thunks in lifted Vector case, use map' if that's not desired.

For PrimVector, map and map' are same, since PrimVectors never store thunks.

map' :: forall u v a b. (Vec u a, Vec v b) => (a -> b) -> u a -> v b Source #

Mapping between vectors (possiblely with two different vector types).

This is the strict version map. Note that the Functor instance of lifted Vector is defined with map to statisfy laws, which this strict version breaks (map' id arrayContainsBottom /= arrayContainsBottom ).

imap' :: forall u v a b. (Vec u a, Vec v b) => (Int -> a -> b) -> u a -> v b Source #

Strict mapping with index.

traverseVec :: (Vec v a, Vec u b, Applicative f) => (a -> f b) -> v a -> f (u b) Source #

traverseWithIndex :: (Vec v a, Vec u b, Applicative f) => (Int -> a -> f b) -> v a -> f (u b) Source #

traverseWithIndex_ :: (Vec v a, Applicative f) => (Int -> a -> f b) -> v a -> f () Source #

foldl' :: Vec v a => (b -> a -> b) -> b -> v a -> b Source #

Strict left to right fold.

ifoldl' :: Vec v a => (b -> Int -> a -> b) -> b -> v a -> b Source #

Strict left to right fold with index.

foldl1' :: forall v a. (Vec v a, HasCallStack) => (a -> a -> a) -> v a -> a Source #

Throw EmptyVector if vector is empty.

foldl1Maybe' :: forall v a. Vec v a => (a -> a -> a) -> v a -> Maybe a Source #

Strict left to right fold using first element as the initial value. return Nothing when vector is empty.

foldr' :: Vec v a => (a -> b -> b) -> b -> v a -> b Source #

Strict right to left fold

ifoldr' :: Vec v a => (Int -> a -> b -> b) -> b -> v a -> b Source #

Strict right to left fold with index

NOTE: the index is counting from 0, not backwards

foldr1' :: forall v a. (Vec v a, HasCallStack) => (a -> a -> a) -> v a -> a Source #

Strict right to left fold using last element as the initial value.

Throw EmptyVector if vector is empty.

foldr1Maybe' :: forall v a. Vec v a => (a -> a -> a) -> v a -> Maybe a Source #

Strict right to left fold using last element as the initial value, return Nothing when vector is empty.

Special folds

concat :: forall v a. Vec v a => [v a] -> v a Source #

O(n) Concatenate a list of vector.

Note: concat have to force the entire list to filter out empty vector and calculate the length for allocation.

concatMap :: Vec v a => (a -> v a) -> v a -> v a Source #

Map a function over a vector and concatenate the results

maximum :: (Vec v a, Ord a, HasCallStack) => v a -> a Source #

O(n) maximum returns the maximum value from a vector

It's defined with foldl1', an EmptyVector exception will be thrown in the case of an empty vector.

minimum :: (Vec v a, Ord a, HasCallStack) => v a -> a Source #

O(n) minimum returns the minimum value from a vector

An EmptyVector exception will be thrown in the case of an empty vector.

maximumMaybe :: (Vec v a, Ord a) => v a -> Maybe a Source #

O(n) maximum returns the maximum value from a vector, return Nothing in the case of an empty vector.

minimumMaybe :: (Vec v a, Ord a) => v a -> Maybe a Source #

O(n) minimum returns the minimum value from a vector, return Nothing in the case of an empty vector.

sum :: (Vec v a, Num a) => v a -> a Source #

O(n) sum returns the sum value from a vector

count :: (Vec v a, Eq a) => a -> v a -> Int Source #

O(n) count returns count of an element from a vector

product :: (Vec v a, Num a) => v a -> a Source #

O(n) product returns the product value from a vector

product' :: (Vec v a, Num a, Eq a) => v a -> a Source #

O(n) product returns the product value from a vector

This function will shortcut on zero. Note this behavior change the semantics for lifted vector: product [1,0,undefined] /= product' [1,0,undefined].

all :: Vec v a => (a -> Bool) -> v a -> Bool Source #

O(n) Applied to a predicate and a vector, all determines if all elements of the vector satisfy the predicate.

any :: Vec v a => (a -> Bool) -> v a -> Bool Source #

O(n) Applied to a predicate and a vector, any determines if any elements of the vector satisfy the predicate.

Building vector

Accumulating maps

mapAccumL :: forall u v a b c. (Vec u b, Vec v c) => (a -> b -> (a, c)) -> a -> u b -> (a, v c) Source #

The mapAccumL function behaves like a combination of map and foldl; it applies a function to each element of a vector, passing an accumulating parameter from left to right, and returning a final value of this accumulator together with the new list.

Note, this function will only force the result tuple, not the elements inside, to prevent creating thunks during mapAccumL, seq your accumulator and result with the result tuple.

mapAccumR :: forall u v a b c. (Vec u b, Vec v c) => (a -> b -> (a, c)) -> a -> u b -> (a, v c) Source #

The mapAccumR function behaves like a combination of map and foldr; it applies a function to each element of a vector, passing an accumulating parameter from right to left, and returning a final value of this accumulator together with the new vector.

The same strictness property with mapAccumL applys to mapAccumR too.

Generating and unfolding vector

replicate :: Vec v a => Int -> a -> v a Source #

O(n) replicate n x is a vector of length n with x the value of every element.

Note: replicate will not force the element in boxed vector case.

cycleN :: forall v a. Vec v a => Int -> v a -> v a Source #

O(n*m) cycleN a vector n times.

unfoldr :: Vec u b => (a -> Maybe (b, a)) -> a -> u b Source #

O(n), where n is the length of the result. The unfoldr function is analogous to the List 'unfoldr'. unfoldr builds a vector from a seed value. The function takes the element and returns Nothing if it is done producing the vector or returns Just (a,b), in which case, a is the next byte in the string, and b is the seed value for further production.

Examples:

   unfoldr (\x -> if x <= 5 then Just (x, x + 1) else Nothing) 0
== pack [0, 1, 2, 3, 4, 5]

unfoldrN :: forall v a b. Vec v b => Int -> (a -> Maybe (b, a)) -> a -> (v b, Maybe a) Source #

O(n) Like unfoldr, unfoldrN builds a vector from a seed value. However, the length of the result is limited by the first argument to unfoldrN. This function is more efficient than unfoldr when the maximum length of the result is known.

The following equation relates unfoldrN and unfoldr:

fst (unfoldrN n f s) == take n (unfoldr f s)

Searching by equality

elem :: (Vec v a, Eq a) => a -> v a -> Bool Source #

O(n) elem test if given element is in given vector.

notElem :: (Vec v a, Eq a) => a -> v a -> Bool Source #

O(n) 'not . elem'

elemIndex :: (Vec v a, Eq a) => a -> v a -> Maybe Int Source #

O(n) The elemIndex function returns the index of the first element in the given vector which is equal to the query element, or Nothing if there is no such element.
