Caveat: since fetches are aborted when a new value is explicitly set in the cache, this can lead to fetch returning a stale value, since that was the fallback valueat the moment thefetch()was initiated, even though the new updated value is now present in the cache. For example: constca...
// LRU cache implementation // // Cache entries have an "in_cache" boolean indicating whether the cache has a // reference on the entry. The only ways that this can become false without the // entry being passed to its "deleter" are via Erase(), via Insert() when // an element w...

LRU cache is used in various open source components. It is often used for hot and cold data and elimination strategies. There are three main points for using LRU. The first point is that the implementation is very simple. The second point is that the amount of code itself is not bad. ...
This implementation aims to be as flexible as possible, within the limits of safe memory consumption and optimal performance. At initial object creation, storage is allocated for max items. If max is set to zero, then some performance is lost, and item count is unbounded. Either maxSize or ...
A note on binomial heaps.I've implemented both a standard binary heap, as well as a binomial heap in Python before. I was not impressed by my binomial heap implementation. The author that you link to claims to have creted a fibonacci heap that is fast...but how fast? The graphs for...
This library offers two different implementations in the form of two classes:resty.lrucacheandresty.lrucache.pureffi. Both implement the same API. The only difference is that the latter is a pure FFI implementation that also implements an FFI-based hash table for the cache lookup, while the ...
