Struct CacheLayer

Source 
pub struct CacheLayer { /* private fields */ }
Expand description

A provider layer that caches RPC responses and serves them on subsequent requests.

In order to initialize the caching layer, the path to the cache file is provided along with the max number of items that are stored in the in-memory LRU cache.

One can load the cache from the file system by calling load_cache and save the cache to the file system by calling save_cache.
