Data.Accessor.Container

Description

This module allows to access elements of arrays, sets and finite maps like elements of records. This is especially useful for working with nested structures consisting of arrays, sets, maps and records.

Maybe we should move it to a separate package, then we would not need to import array and containers package.

array :: Ix i => i -> T (Array i e) eSource

set :: Ord a => a -> T (Set a) Bool Source

Treat a Set like a boolean array.

mapDefault :: Ord key => elem -> key -> T (Map key elem) elemSource

Treats a finite map like an infinite map, where all undefined elements are replaced by a default value.

mapMaybe :: Ord key => key -> T (Map key elem) (Maybe elem)Source

Treats a finite map like an infinite map, where all undefined elements are Nothing and defined elements are Just.

intMapDefault :: elem -> Int -> T (IntMap elem) elemSource

intMapMaybe :: Int -> T (IntMap elem) (Maybe elem)Source
