v0.1.0

Major changes to internals and the crate API. See the updated docs for more information. This should still be considered unstable and use at your own risk.

Highlights

• No longer requires nightly. The generic associated types were interesting in theory but in practice there is few locks and collections to use. Even with GATs being stabilized soon, it seems more practical and ergonomic to implement the API directly and use feature flags where necessary.
• Uses hashbrown::raw for internal storage. In the prior implementation the underlying storage was (for the most part) HashMap<K, V>, but, that required producing a hash twice for any access. Using the lower level API allows some modest performance benefits at the cost of losing the higher-level API.
• Addition of high level functions
  • Map::contains
  • Map::get_owned
  • Map::insert
  • Map::into_iter
  • Map::into_values
  • Map::len
  • Map::try_read
  • Map::remove
  • Shard::get
  • Shard::get_mut
  • Shard::insert
  • Shard::len
  • Shard::remove
• Temporarily dropped support for Sets.
