trie-simple

Trie data structure TMap to hold mapping from list of characters to something, i.e. isomorphic to Map [c] v. This package also contains TSet, which is isomorphic to Set of lists of characters.

This package implements these structures using Map from containers package, and require the character type to be only Ord.

Advantages of using this package over Map or Set are:

• 2x Faster lookup (member) operation
• Retrieving subset of map or set with given prefix
• append, prefixes, and suffixes support
• Can be more memory-efficient (but not always; needs benchmark anyway).
