This library provides a very basic, simple API for the most common redis operations.
While not as comprehensive or flexiable as redis-rs,
it does provide a simpler api for most common use cases and operations as well as automatic internal connection
and subscription (pubsub) handling.
In addition, the entire API is accessible via redis client and there is no need to manage connection or pubsub instances in parallel.
Connection resiliency is managed by verifying the connection before every operation against the redis server.
In case of any connection issue, a new connection will be allocated to ensure the operation is invoked on a valid
connection only.
However, this comes at a small performance cost of PING operation to the redis server.
Subscription resiliency is ensured by recreating the internal pubsub and issuing new subscription requests
automatically in case of any error while fetching a message from the subscribed channels.
This library is still in initial development stage and many more features will come soon.
In order to use this library, you need to first include the crate as follows:
rust
extern crate simple_redis;
Afterwards create a redis client using a connection string:
rust
match simple_redis::create("redis://127.0.0.1:6379/") {
Ok(mut client) => println!("Created Redis Client"),
Err(error) => println!("Unable to create Redis client: {}", error)
}
Once you have a redis client, you can invoke any of the available commands directly or use the run_command function to invoke operations that were not implemented by the library.
````rust match client.set("mykey", "myvalue") { Err(error) => println!("Unable to set value in Redis: {}", error), _ => println!("Value set in Redis") };
match client.get("my_key") { Ok(value) => println!("Read value from Redis: {}", value), Err(error) => println!("Unable to get value from Redis: {}", error) };
/// run some command that is not built in the library
match client.runcommand::
/// publish messages let mut result = client.publish("newschannel", "test message"); assert!(result.isok());
/// subscribe to channels result = client.subscribe("importantnotifications"); assert!(result.isok()); result = client.psubscribe("*notifications"); assert!(result.isok());
loop { /// fetch next message match client.getmessage() { Ok(message) => { let payload: String = message.getpayload().unwrap(); assert_eq!(payload, "my important message") } _ => panic!("test error"), } } ````
In order to use this library, just add it as a dependency:
ini
