Gearman Worker Library for Rust

High level library to implement Gearman workers.

Install

Add this dependency to your Cargo.toml

gearman-worker = "*"

Usage

extern crate gearman_worker;

use gearman_worker::Worker;

fn main() {
    let server_addr = "127.0.0.1:4730".parse().unwrap();

    let mut worker = WorkerBuilder::new("my-worker-rs-1", server_addr).build();
    worker.connect().unwrap();

    worker.register_function("greet", |input| {
        let hello = String::from_utf8_lossy(input);
        let response = format!("{} world!", hello);
        Ok(response.into_bytes())
    }).unwrap();

    worker.run().unwrap();
}

where the worker functions have the following signature:

Fn(&[u8]) -> Result<Vec<u8>, Option<Vec<u8>>>;

Known issues

This has not been tested yet with a real workload and the public interface will probably change in the future.

The worker runs in a single thread using blocking tcp connections. This is fine if you don't expect high concurrency and you can always spawn multiple separate processes to handle the workload but I plan on implementing multi-threading and non-blocking io (probably with tokio).

The following gearman operations are not currently supported but the typical use-case is implemented:

• WORK_STATUS

• CAN_DO_TIMEOUT

• WORK_DATA

• WORK_WARNING

• GRAB_JOB_UNIQ

• GRAB_JOB_ALL
