Using a MySQL pool to pass a connection to the following function hangs after executing the first query and before executing the first iteration of the loop.

use sqlx::prelude::*;
async fn hang(mut conn: sqlx::pool::PoolConnection<sqlx::mysql::MySqlConnection>) {
    let migrations = sqlx::query_as::<_, (String,)>("SELECT attribute FROM attributes")
        .fetch_all(&mut conn)
        .await
        .expect("First Query Failed");
    for m in migrations {
        println!("Here");
        sqlx::query_as::<_, (String,)>("SELECT attribute FROM attributes WHERE attribute = ?")
            .bind(m.0)
            .fetch_all(&mut conn)
            .await
            .expect("Second Query Failed");
        println!("Not Here");
    }
}
