elaru: A simple, fast, and memory safe least-recently-used (LRU) cache.

elaru avoids all unsafe operations while still achieves O(1) performance on insert, get, and remove_lru. fnv feature is also provided for anyone looking for better performance on small key size.

See the documentation for examples and more details.

Acknowledgement: This crate is heavily inspired by uluru, a no_std lru implementation from servo.
