An asynchronous Redis client for Rust.

Documentation

Official Documentation

Philosophy

• Low allocations
• Full async library
• Lock free implementation
• Rust idiomatic API
• Multiplexing as a core feature

Features

• Full documentation with multiple examples
• Support all Redis Commands until Redis 8.0
• Async support (tokio or async-std)
• Different client modes:
  • Single client
  • Multiplexed client
  • Pooled client manager (based on bb8)
• Automatic command batching
• Advanced reconnection & retry strategy
• Pipelining support
• Configuration with Redis URL or dedicated builder
• TLS support
• Transaction support
• Pub/sub support
• Sentinel support
• LUA Scripts/Functions support
• Cluster support (minimus supported Redis version is 6)
• Client-side caching support

Protocol Compatibility

Rustis uses the RESP3 protocol exclusively.

The HELLO 3 command is automatically sent when establishing a connection.
Therefore, your Redis server must support RESP3 (Redis ≥6.0+ with RESP3 enabled).

If you use Redis 5 or older, or your Redis 6+ server still defaults to RESP2,
Rustis will not work.

To verify your server supports RESP3:

redis-cli --raw HELLO 3

If you see server info (role, version, etc.), you're good to go. If you get an error, upgrade Redis.

Basic Usage

use rustis::{
     client::Client, 
     commands::{FlushingMode, ServerCommands, StringCommands},
     Result,
};

#[tokio::main]
async fn main() -> Result<()> {
     // Connect the client to a Redis server from its IP and port
     let client = Client::connect("127.0.0.1:6379").await?;
 
     // Flush all existing data in Redis
     client.flushdb(FlushingMode::Sync).await?;

     // sends the command SET to Redis. This command is defined in the StringCommands trait
     client.set("key", "value").await?;
 
     // sends the command GET to Redis. This command is defined in the StringCommands trait
     let value: String = client.get("key").await?;
     println!("value: {value:?}");

     Ok(())
}
