Crate white_rabbit

“I'm late! I'm late! For a very important date!” by “The White Rabbit” 『Alice's Adventures in Wonderland』

white_rabbit schedules your tasks and can repeat them!

One funny use case are chat bot commands: Imagine a remind me-command, the command gets executed and you simply create a one-time job to be scheduled for whatever time the user desires.

We are using chrono's DateTime<Utc>, enabling you to serialise and thus backup currently running tasks, in case you want to shutdown/restart your application, constructing a new scheduler is doable. However, please make sure your internal clock is synced.

Structs

Context	When a task is due, this will be passed to the task. Currently, there is not much use to this. However, this might be extended in the future.
Date	Every job gets a planned Date with the scheduler.
DateTime	ISO 8601 combined date and time with time zone.
Duration	ISO 8601 time duration with nanosecond precision. This also allows for the negative duration; see individual methods for details.
Scheduler	This scheduler exists on two levels: The handle, granting you the ability of adding new tasks, and the executor, dating and executing these tasks when specified time is met.
Utc	The UTC time zone. This is the most efficient time zone when you don't need the local time. It is also used as an offset (which is also a dummy type).

Enums

DateResult

Every task will return this enum.
