Add try_join to ntex_utils about ntex HOT 4 CLOSED

tokio::try_join!() should work fine

from ntex.

okay, and just a noob question. is possible to use tokio::try_join!(), if the result types are different?

Result Types AppError and Error(external crate). And i can't use try_join!() because the result types are different. But i implemented From<Error> for AppError, exist some way to do it? i have been searching for 1 hour and i didn't find anything. Sorry to ask this :(

let delete_cache_future = self.cache.user.delete(id); // Returns AppError
let update_user_future = conn.execute(&cached_statement, &params[..]); // Returns Error

tokio::try_join!(update_user_future, delete_cache_future); // Error. Different error types

instead of:

let delete_cache_future = self.cache.user.delete(id);
let update_user_future = conn.execute(&cached_statement, &params[..]);

let (db_result, cache_result) = tokio::join!(update_user_future, delete_cache_future);

db_result?;
cache_result?;

you should ask tokio devs, or read tokio docs.
