Fresh Tweak on Open Addressing Hash Maps
In case you are wondering how I know all that stuff, it is mainly because I had to take an algorithms course in university and was forced to learn this. For a while I had wondered if it would be possible to create something like what an `ArrayVec` is to `Vec`, but for HashMaps and began implementing this in https://github.com/Luro02/array-map

Leapfrog 0.2.0 (improved concurrent rust hashmap)
I'm announcing v 0.2.0 of leapfrog (crate), which adds new features and fixes the collision problems of the previous version. The performance is slightly reduced, but not by much and the maps are still very fast.

On my way to make the production rusty
You can try Leapfrog as your concurrent hashmap implementation https://github.com/robclu/leapfrog. I recently stumbled across it and was pleased by its performance

Announcing Leapfrog, a faster concurrent HashMap
For a personal project I needed a concurrent HashMap, so thought I would port one of the fast C++ hashmaps to Rust., which I have called Leapfrog. The API is similar to the HashMap in the std library, but to improve concurrent performance it is slightly different in places.
What are some alternatives?
When comparing array-map and leapfrog you can also consider the following projects:
hashmap-compare - A comparison of standard library and language implementations of hashmaps
dashmap - Blazing fast concurrent HashMap for Rust.
scalable-concurrent-containers - High-performance containers and utilities for concurrent and asynchronous programming
indicium - A simple in-memory search for collections and key-value stores.
