Structured Stream Parallelism for Rust

Define a pipeline with N steps. Pipelines can be normal pipelines or "farm pipelines" (in which some steps are parallel). You can also define pipelines with mutable state.

fn pipelined() {
    let pipeline = pipeline![
        pipeline,
        parallel!(LoadImage, 40),
        parallel!(ApplyMoreSaturation, 2),
        parallel!(ApplyEmboss, 2),
        parallel!(ApplyGamma, 2),
        parallel!(ApplySharpen, 2),
        parallel!(ApplyGrayscale, 2),
        parallel!(SaveImageAndGetResult, 40),
        sequential!(PrintResult)];

    let dir_entries = std::fs::read_dir("/Users/user/Desktop/imagens");

    for entry in dir_entries.unwrap() {
        let entry = entry.unwrap();
        let path = entry.path();

        if path.extension().is_none() { continue; }

        println!("Posting {:?}", path.to_str().unwrap());

        pipeline.post(path).unwrap();
        
    }

    pipeline.end_and_wait();

    println!("Finished.");
}
