Function mutex_run 

pub async fn mutex_run<S, O, E, F>(
    lock_name: S,
    redis: &Redis,
    f: F,
) -> Result<O, E>
where
    S: AsRef<str>,
    F: Future<Output = Result<O, E>>,
    E: From<Error>,

Runs async function exclusively using Redis lock.

Lock will be released even if async block fails.

Errors

This function will return an error if either f call triggers exception, or lock failure. Panic in async call will not release lock, but it will be released after timeout.
