Crate dwrs 

A powerful and flexible file downloader library with parallel downloads, resumable downloads, progress tracking, and desktop notifications.

Features

• Parallel downloads: Split large files into chunks and download concurrently
• Resumable downloads: Continue interrupted downloads from where they left off
• Progress tracking: Visual progress bars with download statistics
• Desktop notifications: Get notified when downloads complete or fail
• File-based batch downloads: Download multiple files from a list
• Configurable concurrency: Control number of workers and parallel files

Quick Start

use dwrs::{Downloader, DownloadConfig};
use std::path::PathBuf;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error + Send + Sync>> {
    // Initialize logging
    dwrs::init();

    // Create downloader with default config
    let downloader = Downloader::new_default();

    // Download a single file
    downloader.download_file(
        "https://example.com/file.zip",
        PathBuf::from("file.zip")
    ).await?;

    Ok(())
}

Configuration

Use DownloadConfig to customize behavior:

use dwrs::DownloadConfig;

let config = DownloadConfig {
    workers: 8,              // Parallel chunks per file
    buffer_size: 512 * 1024, // 512KB buffer
    retries: 5,              // Retry failed downloads
    ..Default::default()
};
