Quick start

use std::path::PathBuf;
use trauma::{download::Download, downloader::DownloaderBuilder, Error};

#[tokio::main]
async fn main() -> Result<(), Error> {
    let reqwest_rs = "https://github.com/seanmonstar/reqwest/archive/refs/tags/v0.11.9.zip";
    let downloads = vec![Download::try_from(reqwest_rs).unwrap()];
    let downloader = DownloaderBuilder::new()
        .directory(PathBuf::from("output"))
        .build();
    downloader.download(&downloads).await;
    Ok(())
}

More examples can be found in the examples folder. They are well commented and will guide you through the different features of this library.

Why another download manager

Before starting this project, I spent some time searching the internet, trying not to reinvent the wheel. And I did find a bunch of interesting existing projects!

However they are almost all abandoned:

• DLM: https://github.com/agourlay/dlm
  • Active, but is just a binary/CLI tool
• Snatch: https://github.com/derniercri/snatch
  • Inactive since Sept '17
  • Recommend switching to Zou
• Zou: https://github.com/k0pernicus/zou
  • Inactive since Oct '17
• Duma: https://github.com/mattgathu/duma
  • Inactive since Nov '20
• Siwi: https://github.com/rs-videos/siwi-download
  • Inactive since Mar '21
• Downloader: https://github.com/hunger/downloader
  • Dying project
  • No answers to issues/PRs
  • Only automated updates are being merged
  • No release since Feb '21

As a result, I decided to write trauma.
