Struct VegaFusionCache 

pub struct VegaFusionCache { /* private fields */ }

The VegaFusionCache uses a Segmented LRU (SLRU) cache policy (https://en.wikipedia.org/wiki/Cache_replacement_policies#Segmented_LRU_(SLRU)) where both the protected and probationary LRU caches are limited by capacity (number of entries) and memory limit.

Implementations
