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).
Benchmarks
Benchmarks compared against plain Map
and Set
.
Each of these benchmarks has two sets of point and errorbars, representing two datasets they are run against.
