Should be checked against official Rust API naming guidelines. LrukCache, not LRUKCache etc.

ah, gad damn it. cheers though :P

Thanks for the link, nice to see the informal conventions spelled out like this!

Would love to see benchmarks vs competition considering the high performance claim. Foyer is another rust hybrid cache, and quick-cache is the fastest in-memory impl I'm aware of.

Sane defaults and easy of setting a memory limit are two other things I look for in caches.

On your example, without reading into the implementation, I'm wondering if the comment is wrong, or if the comment is telling us about a hidden default, but then what does the 2 mean.

    // Create an LRU cache with a capacity of 100 entries
    let mut cache = LRUKCache::new(2);

Why 100? Why not 2?

derp, It should be LRU instead of LRU-K.

Another time I wish rust had named parameters. For reading code without an IDE (which is a lot of the experience in discovering a library, learning, navigating in code on github...) it would be useful.

I think so, too, it's beautifully designed in many ways, but this seems like an oversight.
