Crate clokwerk

Clokwerk, a simple scheduler

Clokwerk is a simple scheduler, inspired by Python’s Schedule and Ruby’s clockwork. It uses a similar DSL for scheduling, rather than parsing cron strings.

Usage

Synchronous

See Scheduler.

Asynchronous

See AsyncScheduler.

Caveats

Some combinations of times or intervals are permissible, but make little sense, e.g. every(10.seconds()).at("16:00"), which would next run at the next 4 PM after the next multiple of 10 seconds.

Similar libraries

• schedule-rs and job_scheduler are two other Rust scheduler libraries. Both use cron syntax for scheduling.

Modules

timeprovider

Structs

AsyncJob

An asynchronous job to run on the scheduler. Create these by calling AsyncScheduler::every().

AsyncScheduler

An asynchronous job scheduler, for use with Futures.

ScheduleHandle

Guard object for the scheduler background thread. The thread is terminated if this object is dropped, or ScheduleHandle::stop() is called

Scheduler

Synchronous job scheduler

SyncJob

A job to run on the scheduler. Create these by calling Scheduler::every().

Enums

Interval

Traits

Job

This trait provides an abstraction over SyncJob and AsyncJob, covering all the methods relating to scheduling, rather than execution.

NextTime

TimeUnits

A trait for easily expressing common intervals. Each method generates an appropriate Interval. Plural and non-plural forms behave identically, but exist to make code more grammatical.
