std :: marker :: Unpin не выполняется

Question

Я пытаюсь заставить работать фьючерсную функцию try_join_all, и я немного застрял. Мой код выглядит следующим образом:

use crate::Client;
use futures::future;
use std::boxed;

const SQL_EXTENSION: &str = "sql";

type ExecuteFileFuture = boxed::Box<dyn future::Future<Output = Result<(), postgres::Error>>>;

pub async fn run_migrations_in_path(
    path: &str,
    client: &mut Client,
) -> Result<(), postgres::Error> {
    let sql_files = files::by_extension(path, SQL_EXTENSION);
    let transaction = client.transaction().await?;
    let migrations: Vec<ExecuteFileFuture> = sql_files
        .iter()
        .map(|file_path| boxed::Box::new(client.execute_file(file_path)) as ExecuteFileFuture)
        .collect();
    future::try_join_all(migrations).await?;
    transaction.commit()
}

Когда я пытаюсь запустить этот код, я получаю следующие ошибки:

Я просматриваю форумы et c, но пока не удалось решить проблему. Я надеюсь, что кто-то может пролить некоторый свет, так как я не уверен, в чем проблема.

Заранее спасибо за любую помощь!
