Description

STm hashmap

Synopsis

Documentation

type TMap a b = Map a b Source #

STM hashmap

Indicate if the map is empty

Get the number of elements in the map

lookup :: Key k => k -> TMap k a -> STM (Maybe a) Source #

Lookup an element in the map from its key

Check if a key is in the map

Check if a key is not in the map

Create an empty map

singleton :: Key k => k -> v -> STM (TMap k v) Source #

Create a map containing a single element

insert :: Key k => k -> v -> TMap k v -> STM () Source #

Insert an element in the map

fromList :: Key k => [(k, v)] -> STM (TMap k v) Source #

Create a new TMap from a list

delete :: Key k => k -> TMap k v -> STM () Source #

Delete an element from the map

Get values

Get keys

(!) :: Key k => TMap k v -> k -> STM v Source #

Unsafe lookup in the map
