Data.Array.IsList
Contents
Description
This package provides "orphan" IsList instances for Arrays
with Integral indices up to 5 dimensions to allow initializing
Arrays from [nested] lists using OverloadedLists GHC extension.
Examples:
>>>["one","two","three"] :: Array Int Stringarray (0,2) [(0,"one"),(1,"two"),(2,"three")]
>>>[[0,1,2], [10,11,12]] :: Array (Int, Int) Intarray ((0,0),(1,2)) [((0,0),0),((0,1),1),((0,2),2),((1,0),10),((1,1),11),((1,2),12)]
If any of the nested lists contains different number of elements for the same dimension, the array creation will fail.
>>>[[1],[2,3]] :: Array (Int, Int) Intarray *** Exception: Error in array index
Documentation
The IsList class and its methods are intended to be used in
conjunction with the OverloadedLists extension.
Since: base-4.7.0.0
Instances
fromList :: IsList l => [Item l] -> l #
The fromList function constructs the structure l from the given
list of Item l
toList :: IsList l => l -> [Item l] #
The toList function extracts a list of Item l from the structure l.
It should satisfy fromList . toList = id.
