I wonder what fast concurrent key/value storage systems (non blocking hash tables and such) there are in Rust.

Especially this looks really impressive: https://www.microsoft.com/en-us/research/uploads/prod/2018/03/faster-sigmod18.pdf

There is concurrent hash table work-in-progress, to be included in Crossbeam. You may want to subscribe to the issue.

There is also evmap.
