How would you download a file?

Hi guys, I am new to Rust and the crate itself. I would really appreciate if you could give me a hint into how I could download a file using isahc.

So downloading a file usually involves making a GET request, so you'd likely use get for that. Then you can pipe the response into a file using the copy_to_file extension method on the response. So an example might look like this:

use isahc::prelude::*;
use std::error::Error;

fn main() -> Result<(), Box<dyn Error>> {
    // Open an HTTP connection to the server and start streaming the file.
    let mut response = isahc::get("https://example.org/some-file-to-download")?;

    // Check if the server returned a success code.
    if response.status().is_success() {
        // Pipe the response stream to a local file.
        response.copy_to_file("some-file-downloaded")?;
    } else {
        println!("Server returned status code {}", response.status());
    }

    Ok(())
}
