Crate ferro_queue 

Cancer Queue

Background job queue system for the Cancer framework.

Provides a Laravel-inspired queue system with support for:

• Redis-backed job queues
• Job delays and retries
• Multiple named queues
• Job chaining
• Graceful shutdown

Example

use cancer_queue::{Job, Queueable, dispatch};
use serde::{Deserialize, Serialize};

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

#[async_trait::async_trait]
impl Job for SendEmail {
    async fn handle(&self) -> Result<(), cancer_queue::Error> {
        println!("Sending email to {}: {}", self.to, self.subject);
        Ok(())
    }
}

// Dispatch a job
SendEmail { to: "user@example.com".into(), subject: "Hello".into() }
    .dispatch()
    .await?;

// Dispatch with delay
SendEmail { to: "user@example.com".into(), subject: "Reminder".into() }
    .delay(std::time::Duration::from_secs(60))
    .on_queue("emails")
    .dispatch()
    .await?;
