genericFoldWithKey :: (GTrieKey (Rep k), Generic k, TrieRep k ~ TrieRepDefault k) => (k -> a -> r -> r) -> r -> Trie k a -> r

Generic implementation of foldWithKey. This is the default implementation.

genericTraverseWithKey :: (GTrieKey (Rep k), Generic k, TrieRep k ~ TrieRepDefault k, Applicative f) => (k -> a -> f b) -> Trie k a -> f (Trie k b)

Generic implementation of traverseWithKey. This is the default implementation.

data TrieRepDefault k a

The default implementation of a TrieRep is GTrie wrapped in a Maybe. This wrapping is due to the GTrie being a non-empty trie allowing all the of the "emptiness" to be represented at the top level for any given generically implemented key.

class GTrieKey f where

TrieKey operations on Generic representations used to provide the default implementations of tries.
