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.

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.

I am not sure of the performance or implementation difficulty but the data structure seems to be what you are talking about.

Writing a concurrent LRU cache
Part 1 makes sense, 2 is a little confusing. The blog post ends up using this Java library: https://github.com/ben-manes/concurrentlinkedhashmap which implements those ideas. I am curious if there is something equivalent implemented in rust, or is it something I should write? Also is there an even better way to do thread-safe performant LRU?
What are some alternatives?
triple-buffer - Implementation of triple buffering in Rust
Caffeine - A high performance caching library for Java
bus - Efficient, lock-free, bounded Rust broadcast channel
moka - A high performance concurrent caching library for Rust
dashmap - Blazing fast concurrent HashMap for Rust.
concache - A linked-list based, lock-free concurrent hashmap in Rust.
evlru - An eventually consistent LRU designed for lock-free concurrent reads
stretto - Stretto is a Rust implementation for Dgraph's ristretto (https://github.com/dgraph-io/ristretto). A high performance memory-bound Rust cache.
