Dhall.Set

Description

This module only exports ways of constructing a Set, retrieving List, Set, and Seq representations of the same data, as well as a novel "difference" function. Any other Set-like or List-like functionality should be obtained through toSet and toList, respectively.

Synopsis

- data Set a = Set (Set a) (Seq a)
- toList :: Set a -> [a]
- toAscList :: Set a -> [a]
- toSet :: Set a -> Set a
- toSeq :: Set a -> Seq a
- fromList :: Ord a => [a] -> Set a
- fromSet :: Set a -> Set a
- append :: Ord a => a -> Set a -> Set a
- empty :: Set a
- difference :: Ord a => Set a -> Set a -> [a]
- sort :: Ord a => Set a -> Set a
- isSorted :: Ord a => Set a -> Bool
- null :: Set a -> Bool
- size :: Set a -> Int

# Documentation

data Set a #

This is a variation on `Data.Set.`Set`` that remembers the original order of elements. This ensures that ordering is not lost when formatting Dhall code

Constructors

Set (Set a) (Seq a) |

toList :: Set a -> [a] #

Convert a `Set` to a list, preserving the original order of the elements

toAscList :: Set a -> [a] #

Convert a `Set` to a list of ascending elements

toSet :: Set a -> Set a #

Convert to an unordered `Data.Set.`Set``

toSeq :: Set a -> Seq a #

Convert to an ordered `Seq`

fromList :: Ord a => [a] -> Set a #

Convert a list to a `Set`, remembering the element order

fromSet :: Set a -> Set a #

Convert a `Data.Set.`Set`` to a sorted `Set`

append :: Ord a => a -> Set a -> Set a #

Append an element to the end of a `Set`

empty :: Set a #

The empty `Set`

difference :: Ord a => Set a -> Set a -> [a] #

Returns, in order, all elements of the first Set not present in the second. (It doesn't matter in what order the elements appear in the second Set.)

sort :: Ord a => Set a -> Set a #

Sort the set elements, forgetting their original ordering.

    >>> sort (fromList [2, 1]) == fromList [1, 2]
    True

isSorted :: Ord a => Set a -> Bool #

    >>> isSorted (fromList [2, 1])
    False
    >>> isSorted (fromList [1, 2])
    True

null :: Set a -> Bool #

    >>> null (fromList [1])
    False
    >>> null (fromList [])
    True

size :: Set a -> Int #

    >>> size (fromList [1])
    1
