camunda-external-task-client

Camunda external task client implemented using the rust language.

State of the project

The project is not complete, but it is already in a usable state. You can use the client to subscribe to topics and complete tasks.

Installing

The project is not available on crates.io yet, so the only way to use it right now is via github url:

[dependencies]
camunda-external-task-client = { git = "https://github.com/danielkelemen/camunda-external-task-client-rust" }

Usage

use camunda_external_task_client_rust::*;

fn main() -> Result<()> {
    // activate logger
    env_logger::builder().filter_level(LevelFilter::Info).init();

    // configure client
    let config = Config::new("http://localhost:8080/engine-rest")
        .with_interval(1000)
        .with_max_tasks(100);
    let mut client = Client::new(config)?;

    // subscribe to topic
    client
        .subscribe("invoiceCreator")
        .handler(|task: &Task, engine_service: &EngineService| {
            info!("received task {}", task.id);
        })
        .open()?;

    // wait for client thread
    client.join()?;

    Ok(())
}
