PooledConn with mysql 25 error

[JonasFocke01]

Hello,
im seeing an error i cant explain or find fixes on the internet. Can you help me here?

Im using this packages in my Cargo.toml:

mysql = "25.0.1"
refinery = { version = "0.8.14", features = ["mysql"]}

The mysql initialization happens flawlessly:

let url = format!(
    "mysql://my_usr:my_pass@localhost:3306/{}",
    if cfg!(debug_assertions) {
        "my_db_dev"
    } else {
        "my_db"
    }
);
let Ok(pool) = Pool::new(url.as_str()) else {
    ...
    std::process::exit(1);
};
let Ok(mut db_connection) = pool.get_conn() else {
    ...
    std::process::exit(1);
};

But creating the migrations like this

refinery::embed_migrations!("./src/database_handler/migrations"); // compiles without errors
migrations::runner().run(&mut db_connection).unwrap(); // compile time error

Results in an error, that tells me, that the mysql::PooledConn is not implementing refinery::Migrate. Only mysql::conn::pool::PooledConn is implementing it. I poked around a bit but have not found a solution to my problem. Can you help me?
