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.

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.

Hyperbridge: Fast multi-producer, multi-consumer unbounded channel in Rust
Crossbeam isn't async[0]. It can multiplex with itself (via the `select!` macro), but not with anything else.

Where can I read about how to write a safe API for unsafe code?
Shooting from the hip, crossbeam might be a good candidate for understanding the thread safety aspects of Rust. I kind of feel like this is probably "too big" of a project if you're just learning, but I can't think of something smaller off the top of my head that would be suitable.

multi-producer multi-consumer channels for message passing python library
I am familiar with crossbeam channels, but now I need to work with python, and I was looking for a similar library.

I needed to write a simple multi-threaded message processing queue in C++ today. Makes me really appreciate how easy this is to do in Rust.
In the C++ example you create a naive mpsc queue using a std queue and a mutex, while in the rust example you use `std::sync::mpsc` which is now implemented internally using https://github.com/crossbeam-rs/crossbeam .

How would one go about updating in-memory storage lock free, while other threads read?
From this project: https://github.com/crossbeam-rs/crossbeam
- This implementation is actually unsafe since we don't check if the index is in-bounds. But this is fine since this is only used internally.
