Writing a concurrent LRU cache
Concache ( https://github.com/saligrama/concache ) is the only crate that came up easily in a search, but I don't know whether it would be easily adaptable if it needed tweaks. You might could try forking it anyway.

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.
What are some alternatives?
When comparing concache and stretto you can also consider the following projects:
concurrentlinkedhashmap - A ConcurrentLinkedHashMap for Java
ristretto - A high performance memory-bound Go cache
