sched

lool » sched is a utility library that provides a way to schedule tasks in various ways. Supports std::thread and the tokio runtime (as a feature flag).

Installation

This library is for internal use. And as such, it's only published privately.

cargo add lool --registry=lugit --features sched {sub-feature}

Sub-Features

Runtimes

At least one of the following features must be enabled to use this library.

•    sched.tokio: Enables the tokio runtime support.

•    sched.threads: Enables the std::thread runtime support.

•    sched.thread-pool: Enables the std::thread runtime support with a thread pool 

Scheduling Rules

The default way to schedule tasks is to use a DateTime object. However, that means that the task will only run once. To schedule tasks to run at specific intervals, you can use the following features:

•    sched.rule-recurrent: Enables the "recurrent-rule" style for scheduling tasks.

•    sched.rule-cron: Enables the "cron-like" style for scheduling tasks

Planned Features

• sched.rule-pyschedule: Enables the python schedule-like style for scheduling tasks
• sched.thread-pool: Enables the std::thread runtime support with a thread pool (like scheduled-thread-pool crate but using lool's thread pool implementation)

Usage

Check the examples directory for usage examples:

• tokio: using the tokio runtime
• threads: using the std::thread runtime

Inspiration

This library is inspired by several other libraries, including:

• node-schedule: where the idea of recurring rules was taken from.
• tokio-schedule: tokio async scheduler
• schedule-rs: simple thread-based scheduler
• croner-rust: a croner parser for rust
• job_scheduler: another thread-based job scheduler for rust
• python's schedule: a simple python scheduler with a human-friendly API
