reqwest

reqwest⮳ is a full-fat HTTP client. It can be used in both synchronous and asynchronous code. It requires the tokio⮳ runtime.

Multiple examples using reqwest are found in APIs, Download, Requests.

ureq

ureq⮳ is a minimal synchronous HTTP client, focused on simplicity and minimizing dependencies.

/// This example demonstrates a simple HTTP GET request using the `ureq` crate.
/// It fetches data from a public API endpoint and prints the response.
fn main() -> anyhow::Result<()> {
    // Define the URL to fetch data from.
    let url = "https://jsonplaceholder.typicode.com/posts/1";
    // Send a GET request to the URL and read the response body as a string.
    let response: String =
        // Make a GET request.
        ureq::get(url)
        // Send the request and blocks the caller until we receive a response.
        .call()?
        // Return a mutable reference to the associated HTTP body.
        .body_mut()
        .read_to_string()?;

    println!("Response: {}", response);
    Ok(())
}

Build a HTTP Client with hyper

hyper⮳ is a HTTP/1 and HTTP/2 implementation (both client and server) that works best with the tokio⮳ async runtime, but can support other runtimes.

hyper⮳ is meant to be a low-level building block and is indeed used by higher-level libraries such as curl⮳, reqwest⮳, and aws-sdk. You will likely reach for hyper⮳ to design such tools or access to bleeding-edge features (like HTTP/3).
