Fang

Fang is a background task processing library designed for Rust, utilizing Postgres as a task queue. It offers both asynchronous and threaded workers, allowing tasks to be processed in threads or tokio tasks. Users can schedule tasks at any future time and also set up periodic tasks using cron expressions. Fang ensures that unique tasks are not duplicated in the queue. While tasks are stored in a single table, workers are designed to execute only specific types of tasks. Fang is an open-source project, licensed under MIT, and developed by Ayrat Badykov and Pepe Márquez.
