Struct RedisCache

pub struct RedisCache { /* private fields */ }

Available on crate feature redis only.

Cache using redis.

It uses redis::Client to connect to redis. Feature redis must be enabled.

A custom map should be specified. It will be used as the map of the redis key.

RedisCache implements Cache. See Cache for more details.

Example

let client = redis::Client::open("redis://127.0.0.1:6379/").unwrap();
 
// `aaa` is the hash map name
let map = "aaa";
let cache = RedisCache::new(client, map).await.unwrap(); 
 
cache.set("a", 1).await.unwrap();
assert_eq!(cache.get::<u8>("a").await.unwrap().unwrap(), 1);
 
// Redis Data ('aaa' is a redis hash map):
// aaa: a -> Encoded(1)
