Crate client_util

client-util

Help you to build requests and handle responses by several extension trait!

Usage

cargo add client-util

Make it easier to use hyper http client

use client_util::prelude::{RequestBuilderExt, RequestExt, ResponseExt, hyper_tls_client};
#[tokio::main]
async fn main() -> client_util::Result<()> {
    let mut client = hyper_tls_client();

    let request = http::Request::get("https://httpbin.org/json")
        .version(http::Version::HTTP_11)
        .json("hello client-util")?;

    let (parts, response) = request
        .send(&mut client)
        .await?
        .json::<serde_json::Value>()
        .await?
        .into_parts();
    println!("{:?}", parts);
    println!("{:?}", response);

    Ok(())
}

Customize your own client

In RequestExt trait, we send the request by a tower service, so you can add any middle layer on the top of the existed client.

What about…

Theoretically, you can add any feature to any client by using tower.

What about trace, metrics, following redirect and more features?

You can find those features in tower-http crate as tower layers.

What about cookies?

Implement a tower layer to manage cookies is a good idea, and we may implement in another crate in the future.
