README
treap
Package treap implements an immutabe sorted set datastructure using a combination tree/heap or treap.
The algorithms are mostly based on Fast Set Operations Using Treaps
Although the package is oriented towards ordered sets, it is simple to convert it to work as a persistent map. There is a working example showing how to do this.
Benchmark stats
The most interesting benchmark is the performance of insert where a single random key is inserted into a 5k sized map. As the example shows, the treap structure does well here as opposed to a regular immutable map (using full copying). This benchmark does not take into account the fact that the regular maps are not sorted unlike treaps.
The intersection benchmark compares the case where two 10k sets with 5k in common being interesected. The regular map is about 30% faster but this is still respectable showing for treaps.
