Aide-De-Camp is a backend agnostic delayed job queue. Very similar to girl_friday from the Ruby world.

Notable features:

• Asynchronous. Built from the ground-up using async/await for maximum concurrency.
• Backend agnostic¹. This crate won't force you to run any additional software you don't want to.
• Flexible scheduling. Schedule your job to run right now, in time relative to now or at a specific future time.
• Binary Payloads. Job payloads serialized with bincode for maximum speed and space efficiency.
• Concurrency limits. Specify desired concurrency for each runner.
• Job Router. Run as many job types as you want and limit which runners can process which jobs.
• Cross Platform. Runs anywhere rust has standard lib.
• Traced. All important functions are instrumented.

Pick a backend¹ that suits you and add following to your Cargo.toml:

# Cargo.toml

[dependencies]
aide-de-camp = "0.1.0"
aide-de-camp-sqlite = "0.1.0"  # Or any other available backend

aide-de-camp-sqlite has a pretty detailed example of how to use this crate.

• core. Traits and error types meant to be used by aide-de-camp ecosystem.
• runner. Optional module (runner feature enabled by default) that contains default implementations of runner, job router and types required for their work.
