Description

Synopsis

newtype Assoc k v = Assoc (HashMap k v)
asHashMap :: Functor f => (HashMap k v -> f (HashMap k' v')) -> Assoc k v -> f (Assoc k' v')
fromHashMap :: HashMap k v -> Assoc k v
toHashMap :: Assoc k v -> HashMap k v
toEntries :: Assoc k v -> [(k, v)]

Documentation

newtype Assoc k v Source #

An associative mapping of keys to values.

Currently implemented as a HashMap, this newtype wrapper allows us to:

1) Add non-orphan instances to the underlying structure. 2) Change the underlying type if needed.

Constructors

Assoc (HashMap k v)

fromHashMap :: HashMap k v -> Assoc k v Source #

Convert a HashMap to an Assoc.

toHashMap :: Assoc k v -> HashMap k v Source #

Convert an Assoc to a HashMap.

toEntries :: Assoc k v -> [(k, v)] Source #

Convert an Assoc into a list of key/value pairs.
