- Here are some of the fang's key features:
-
- - Async and threaded workers.
-   Workers can be started in threads (threaded workers) or `tokio` tasks (async workers)
- - Scheduled tasks.
-   Tasks can be scheduled at any time in the future
- - Periodic (CRON) tasks.
-   Tasks can be scheduled using cron expressions
- - Unique tasks.
-   Tasks are not duplicated in the queue if they are unique
- - Single-purpose workers.
-   Tasks are stored in a single table but workers can execute only tasks of the specific type
- - Retries.
-   Tasks can be retried with a custom backoff mode

 ### Defining a task
 
 #### Blocking feature

 Every task should implement the `fang::Runnable` trait which is used by `fang` to execute it.
 
 If you have a `CustomError`, it is recommended to implement `From<FangError>`. So this way you can use [? operator](https://stackoverflow.com/questions/42917566/what-is-this-question-mark-operator-about#42921174) inside the `run` function available in `fang::Runnable` trait.
