        let mut connection = pool.get().await?;
        let channel = connection.create_channel().await?;
        channel.basic_publish(
            "",

            BasicPublishOptions::default(),
            b"hello from deadpool",
            BasicProperties::default(),
        ).await?;
    }
    Ok(())
}

§Example with config, dotenvy and tokio-amqp crate

use std::sync::Arc;

use deadpool_lapin::Runtime;
use deadpool_lapin::lapin::{
    options::BasicPublishOptions,
    BasicProperties,
};
use dotenvy::dotenv;

#[derive(Debug, serde::Deserialize)]
struct Config {
    #[serde(default)]
    amqp: deadpool_lapin::Config
}

impl Config {
    pub fn from_env() -> Result<Self, config::ConfigError> {
         config::Config::builder()
            .add_source(config::Environment::default().separator("__"))
            .build()?
            .try_deserialize()
    }
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    dotenv().ok();
    let mut cfg = Config::from_env().unwrap();
    let pool = cfg.amqp.create_pool(Some(Runtime::Tokio1)).unwrap();
    for _ in 1..10 {
        let mut connection = pool.get().await?;
        let channel = connection.create_channel().await?;
        channel.basic_publish(
            "",
            "hello",
            BasicPublishOptions::default(),
            b"hello from deadpool",
            BasicProperties::default(),
        ).await?;
