# The following are all optional configurations
= 10000 # Connection timeout, in milliseconds
= 1000 # Response timeout, in milliseconds

Component
After configuring the above configuration items, the plugin will automatically register a Redis
connection management object. This object is an alias of redis::aio::ConnectionManager
.
pub type Redis = ConnectionManager;
Extract the Component registered by the plugin
The RedisPlugin
plugin automatically registers a connection management object for us. We can use Component
to extract this connection pool from AppState. Component
is an axum extractor.
async
cache
macro
spring-redis
provides a transparent cache for asynchronous functions based on Redis. Add the cache
macro to the async method to cache the function result.
The example is as follows:
async
Where expire
is an optional parameter.
The function wrapped by cache
must meet the following requirements:
- Must be
async fn
- Can return
Result<T, E>
or a normal valueT
- The return type must implement
serde::Serialize
andserde::Deserialize
, and the underlyingserde_json
is used for serialization
