Struct FifoCache 

pub struct FifoCache { /* private fields */ }

A FIFO cache, that shares global state along all incoming requests of a policy.

As the name suggests, a FIFO eviction strategy is used, meaning that when the maximum number of entries is reached, the first added cache entries will be the first to be evicted.
