Deadpool manager for asynchronous Redis connections

redis-async-pool implements a deadpool manager for asynchronous connections of the redis crate. Connections returned by the pool can be used as regular redis::aio::Connection.

Foreword

You may not need of a pool of async connections to Redis. Depending on your workload, a multiplexed connection will be way faster. Using the ConnectionManager provided by the redis crate, you can achieve very high performances without pooling connections.

Features

runtime agnostic (tested with tokio & async-std)
optional check of connection on recycle
optional ttl on connections

Example

use redis::AsyncCommands;
use redis_async_pool::{RedisConnectionManager, RedisPool};

// Create a pool of maximum 5 connections, checked on reuse without ttl.
let pool = RedisPool::new(
    RedisConnectionManager::new(redis::Client::open("redis://localhost:6379")?, true, None),
    5,
);

// get a connection with the get() async method and use it as regular redis connection
let mut con = pool.get().await?;
con.set(b"key", b"value").await?;
let value: Vec<u8> = con.get(b"key").await?;
assert_eq!(value, b"value");

You can set a ttl for each created connection by the pool, this helps avoiding huge memory consumption when keeping many connections open during a too long time.
