EverySet

A set of unique values. The values can be any type, as the implementation is based on AssocList

Sets

type EverySet a

Represents a set of unique values. So (Set Int) is a set of integers and (Set String) is a set of strings.

Build

empty : EverySet a

Create an empty set.

singleton : a -> EverySet a

Create a set with one value.

insert : a -> EverySet a -> EverySet a

Insert a value into a set.

remove : a -> EverySet a -> EverySet a

Remove a value from a set. If the value is not found, no changes are made.

Query

isEmpty : EverySet a -> Bool

Determine if a set is empty.

member : a -> EverySet a -> Bool

Determine if a value is in a set.

size : EverySet a -> Int

Determine the number of elements in a set.

Combine

union : EverySet a -> EverySet a -> EverySet a

Get the union of two sets. Keep all values.

intersect : EverySet a -> EverySet a -> EverySet a

Get the intersection of two sets. Keeps values that appear in both sets.

diff : EverySet a -> EverySet a -> EverySet a

Get the difference between the first set and the second. Keeps values that do not appear in the second set.

Lists

toList : EverySet a -> List a

Convert a set into a list, sorted from lowest to highest.

fromList : List a -> EverySet a

Convert a list into a set, removing any duplicates.

Transform

map : (a -> a2) -> EverySet a -> EverySet a2

Map a function onto a set, creating a new set with no duplicates.

foldl : (a -> b -> b) -> b -> EverySet a -> b

Fold over the values in a set, in order from lowest to highest.

foldr : (a -> b -> b) -> b -> EverySet a -> b

Fold over the values in a set, in order from highest to lowest.

filter : (a -> Bool) -> EverySet a -> EverySet a

Create a new set consisting only of elements which satisfy a predicate.

partition : (a -> Bool) -> EverySet a -> ( EverySet a, EverySet a )

Create two new sets; the first consisting of elements which satisfy a predicate, the second consisting of elements which do not.
