simple_jobs

Very simple persistent jobs

A simple wrapper for Tokio tasks, where the tasks are saved to a backend of choice, and they can be queried for their status.

As an example, the crate provides the implementation for saving tasks to the filesystem.

Defining the backend

The trait [Job] requires the functions [Job::save] and [Job::load] that save and restore the struct [JobInfo].

Using the [FSJob] implementation

The struct [FSJob] implements the trait [Job] by saving and restoring the job information from the filesystem. Each job gets a unique file, constructed from the unique job id.

Example:

async fn example() -> std::io::Result<()> {
    let job: FSJob<u16, MyError> = FSJob::new("/tmp".into());
    let id = job.submit(|id, job| async move {
        Ok(0u16)
    })?;
    let info = job.load(id)?;
    println!("Job status: {:?}", info.status);
    Ok(())
}
