An HTTP GET in Rust

reqwest's async client: send the request, await the body.

#[tokio::main]
async fn main() -> Result<(), reqwest::Error> {
    let body = reqwest::get("https://typestar.io/healthz")
        .await?
        .text()
        .await?;

    println!("{} bytes", body.len());
    println!("{}", body.trim());
    Ok(())
}

How it works

1. get builds and sends in one call.
2. text awaits the whole body as a String.
3. Both the request and the body read are await points.
