The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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

Tolower() with AVX-512
There's a debate on how unsafe/unsound this technique actually is. https://github.com/ogxd/gxhash/issues/82
I definitely see the conundrum since the dangerous code is such a huge performance gain.

GxHash is a fast and robust non-cryptographic hashing algorithm
I've done some security testing against this hash function. Does anyone care to follow up and see if they can extend the attacks I describe[1]?

GxHash - A new (extremely) fast and robust hashing algorithm 🚀
If you are interested, I invite you to take a look at the preprint paper and the rust source code in the same repository, because yes, this is all open source! Don't hesitate to share insights, I'm looking forward to discussing this in detail with you 😊

What are some alternatives?
When comparing array-map and gxhash you can also consider the following projects:
hashmap-compare - A comparison of standard library and language implementations of hashmaps
smhasher - Hash function quality and speed tests
leapfrog - Lock-free concurrent and single-threaded hash map implementations using Leapfrog probing. Currently the highest performance concurrent HashMap in Rust for certain use cases.
aHash - aHash is a non-cryptographic hashing algorithm that uses the AES hardware instruction
scalable-concurrent-containers - High-performance containers and utilities for concurrent and asynchronous programming
charcoal - Faster utf8.Valid using multi-byte processing without SIMD.
