elif-queue

Background job queue system for the elif.rs framework.

Features

• Multi-backend support: Memory and Redis queue backends
• Job persistence: Reliable job storage and recovery
• Priority queuing: Support for job priorities and delays
• Async-first: Built for modern async Rust applications
• Type-safe: Generic job definitions with serialization support
• Retry logic: Built-in failure handling and retry mechanisms

Quick Start

use elif_queue::{Queue, MemoryBackend, QueueConfig, Job, JobResult};
use std::time::Duration;
use serde::{Serialize, Deserialize};
use async_trait::async_trait;

#[derive(Debug, Clone, Serialize, Deserialize)]
struct EmailJob {
    to: String,
    subject: String,
    body: String,
}

#[async_trait]
impl Job for EmailJob {
    async fn execute(&self) -> JobResult<()> {
        // Send email logic here
        println!("Sending email to: {}", self.to);
        Ok(())
    }

    fn job_type(&self) -> &'static str {
        "email"
    }
}

# tokio_test::block_on(async {
// Create a memory-based queue
let queue = Queue::new(MemoryBackend::new(QueueConfig::default()));

// Enqueue a job
let job = EmailJob {
    to: "user@example.com".to_string(),
    subject: "Hello".to_string(),
    body: "Hello, World!".to_string(),
};

queue.enqueue(job, None).await.unwrap();

// Process jobs
if let Some(job_entry) = queue.dequeue().await.unwrap() {
    let result = job_entry.execute::<EmailJob>().await;
    queue.complete(job_entry.id(), result).await.unwrap();
}
# });
