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.

Low latency queues in Rust ecosystem
I've been researching how low latency I can get with Rust and if there's anything already built. If I limit the question only to SPSC queues, it looks like crossbeam-channel is the most performant one and needs around 20ns per item. In comparison to e.g. https://github.com/Deaod/spsc_queue with almost 1ns/item (the linked queue is not implemented in Rust and only used as an example of what's physically possible). I don't see why we couldn't have something like that in the Rust ecosystem and am wondering if there are any other places to look for perf structures like that, other than Github or crates.io (or they live under a different tag). Also if I would go for a c++ queue, can somebody share the perf impact of calling it from Rust? Haven't done that yet.

A collection of lock-free data structures written in standard C++11
Should be benchmarked against ->

If proven faster OK.. If not.. Well.. back to the drawing board.

Atomics and Concurrency
If you're interested about lock-free data structures, I wrote [lockfree](https://github.com/DNedic/lockfree) a collection of lock-free data structures meant to be readable and both hosted system and embedded friendly.

Optimizing a Ring Buffer for Throughput
If you want more than a spsc queue, I've written `lockfree`, a collection of SPSC and MPMC data structures along the same principles the author here used:https://github.com/DNedic/lockfree.
The library is written in standard C++11 (but additional API's for higher C++ versions have been added), uses no dynamic allocation and is configurable so it is both big metal and deeply embedded friendly.

- A lot of code won't work for types with no default constructors, but that is at least compile error
- Using memcpy[0] for arbitrary types is just wrong, see [1]
