pub struct MemoryCache { /* private fields */ }
Expand description
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);
