Module jobs 

Available on crate feature jobs only.

Background job queue for one-shot, fire-and-forget work triggered from request handlers — e.g. “send a confirmation email after signup” — without blocking the response.

Two flavors:

• JobQueue — an in-memory worker pool. Simple and dependency-free, but queued and retrying jobs are lost if the process crashes or restarts.
• PersistentJobQueue (requires a model-sqlite / model-postgres / model-mysql feature) — persists jobs via the model layer so pending and retrying jobs survive a restart.

Example

use rust_web_server::jobs::JobQueue;

let queue = JobQueue::new(4); // 4 worker threads
queue.submit(|| {
    println!("sending welcome email...");
    Ok(())
});
queue.join(); // wait for in-flight jobs to finish (tests/shutdown only)

Structs

JobQueue

An in-memory background job queue backed by a fixed-size worker pool.

PersistentJobQueuemodel-mysql or model-postgres or model-sqlite

A job queue backed by the model layer (model-sqlite / model-postgres / model-mysql): jobs are written to a rws_jobs table before being acknowledged, so pending and retrying jobs survive a process crash or restart.

Traits

Job

A unit of background work.
