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.

Stretto 0.5.0 release: Support runtime agnostic AsyncCache
Hi, I think this link is a good explanation https://github.com/al8n/stretto/pull/7

Writing a concurrent LRU cache
Ya, I saw concache but I looked into it and it doesn't implement what is needed. Each bucket has its own linked-list backing (hence "lock-free linked list buckets"). An LRU needs each value in each bucket to be part of one linked list I believe. After posting this I realized my line of research was failing because it was state of the art five years ago. Caffeine replaced `concurrentlinkedhashmap` in the java world (by the same author). A rust version of that is Moka. These are much more complicated than a concurrent LRU but faster (aka more state of the art). Another rust crate is Stretto which is a port of dgraph's Ristretto (in go). The question becomes is it worth it to essentially port `concurrentlinkedhashmap` to have a great concurrent LRU when there are more state of the art caches out there.

Stretto - a thread-safe, high-performance, high hit-ratio cache.
For the case in the benches folder(a very roughly bench case), stretto is around 20 - 30 ms(sync version is around 30 - 40 ms) faster than moka, for 120, 000+ operations. I set stretto to collect metrics when benching, collecting metrics will make around 10% overhead. Moka seems not to provide a configuration to collect the metrics, so the hit-ratio is not compared.

SQLite: Wal2 Mode
Very similar to the left-right pattern.

I wanna be a crab.
C is much better specified than unsafe Rust. Some things are just not worked out yet in Rust. This may sometimes even bite very experienced devs, such as this issue with Box's aliasing semantics, which tripped up the author of left-right.

Do you mean this? https://github.com/jonhoo/left-right
I am not sure of the performance or implementation difficulty but the data structure seems to be what you are talking about.
