🚀 Quick Start

Installation

# From crates.io
cargo install turbo-cdn

# Or from source
git clone https://github.com/loonghao/turbo-cdn.git
cd turbo-cdn
cargo build --release

CLI Usage

# Smart download (default - auto-selects best method)
turbo-cdn dl "https://github.com/BurntSushi/ripgrep/releases/download/14.1.1/ripgrep-14.1.1-x86_64-pc-windows-msvc.zip"

# Get optimized CDN URL
turbo-cdn optimize "https://github.com/user/repo/releases/download/v1.0/file.zip"

# Download with verbose output
turbo-cdn dl "https://example.com/file.zip" --verbose

# View performance statistics
turbo-cdn stats

Optional self-update command: enable during install with cargo install turbo-cdn --features self-update to use turbo-cdn self-update / turbo-cdn upgrade.

Stats command status: currently prints a readiness summary; detailed metrics will ship in upcoming releases.

Library Usage

use turbo_cdn::*;

#[tokio::main]
async fn main() -> turbo_cdn::Result<()> {
    let downloader = TurboCdn::new().await?;
    
    let result = downloader.download_from_url(
        "https://github.com/user/repo/releases/download/v1.0/file.zip"
    ).await?;
    
    println!("Downloaded {} bytes at {:.2} MB/s", 
        result.size, result.speed / 1024.0 / 1024.0);
    Ok(())
}
