Description

Mutable Set data structure in IO.

A JavaScript Set. This is a convenience for manipulating JavaScript data structures from Haskell.

We recommend using this module qualified.

import qualified Miso.Data.Set as M

Construction

new :: IO (Set key) Source #

Constructs a new JS Set in IO.

fromList :: ToJSVal key => [key] -> IO (Set key) Source #

Construct a Set from a list of key value pairs.

Operations

insert :: ToJSVal key => key -> Set key -> IO () Source #

Inserts a value into the Set by key.

member :: ToJSVal key => key -> Set key -> IO Bool Source #

Checks existence of key in Set, returns t'Bool.

clear :: Set key -> IO () Source #

Empties the Set.

size :: Set key -> IO Int Source #

Return the size of Set.

delete :: ToJSVal key => key -> Set key -> IO Bool Source #

Removes an entry from a list, returns if the value was removed as Bool.

union :: ToJSVal key => Set key -> Set key -> IO (Set key) Source #

The union of two Set

intersection :: ToJSVal key => Set key -> Set key -> IO (Set key) Source #

The intersection of two Set

difference :: ToJSVal key => Set key -> Set key -> IO (Set key) Source #

The symmetric difference of two Set

isSubset :: ToJSVal key => Set key -> Set key -> IO Bool Source #

Checks if one Set is a subset of another Set

isSuperset :: ToJSVal key => Set key -> Set key -> IO Bool Source #

Checks if one Set is a superset of another Set

isDisjoint :: ToJSVal key => Set key -> Set key -> IO Bool Source #

Checks if one Set is disjoint from another Set
