### Code

```Rust
use std::{net::SocketAddr, future::Future, sync::Arc};

use warp::{reply::Reply, Filter};

use sqlx::postgres::Postgres;

fn login<'a>(
    db: impl sqlx::Acquire<'a, Database = sqlx::Postgres> + Send + 'a,
) -> impl Future<Output = ()> + Send + 'a {
    async move {
        sqlx::query_scalar::<Postgres, i64>("")
        .fetch_one(&mut *db.acquire().await.unwrap())
        .await
        .unwrap();
    }
}

#[tokio::main(flavor = "current_thread")]
async fn main() {
    let db = Arc::new(sqlx::postgres::PgPool::connect("").await.unwrap());

    let app = warp::path!()
        .then(move || {
            let db = db.clone();
            async move {
                login(&mut db.begin().await.unwrap()).await;
                "".into_response()
            }
        });

    warp::serve(app).run(SocketAddr::new([0, 0, 0, 0].into(), 8080)).await;
}
```

with the dependencies
```toml
sqlx = { version = "0.7", features = [ "runtime-tokio-rustls", "postgres" ] }
tokio = { version = "1", features = [ "rt", "macros" ] }
warp = "0.3"
```

bug also exists in the beta or nightly versions.
