-A hash table with consistent order and fast iteration.
-
-The indexmap is a hash table where the iteration order of the key-value
-pairs is independent of the hash values of the keys. It has the usual
-hash table functionality, it preserves insertion order except after
-removals, and it allows lookup of its elements by either hash table key
-or numerical index. A corresponding hash set type is also provided.
-
-This crate was initially published under the name ordermap, but it was renamed to
-indexmap.
