Struct MemoryCache 

pub struct MemoryCache { /* private fields */ }

Cache using memory.

Data is stored in memory. However, this cache will serialize and deserialize data, so it may not be so efficient.

MemoryCache implements Cache. See Cache for more details.

Example

let cache = MemoryCache::default();
 
cache.set("a", 1).await.unwrap();
assert_eq!(cache.get::<u8>("a").await.unwrap().unwrap(), 1);
