ordered-multimap 0.2.0

Insertion ordered multimap

ordered-map-rs

LICENSE Build Status

Currently, this crate contains a single type ListOrderedMultimap. This is a multimap meaning that multiple values can be associated with a given key, but it also maintains insertion order across all keys and values.

Nightly is required due to the use of the hashmap raw entry API.

Documentation

Performance

Preliminary benchmarks show that performance is quite decent but more will be required to state anything definitive.

TODO

It is planned that a corresponding SetOrderedMultimap will also be included in this crate which will provide the same insertion order guarantees, but the set of values associated to a given key will be an actual set instead of a list.
