Posting a body in Rust

A POST with JSON, headers and a bearer token, built up on the request.

use serde::Serialize;

#[derive(Serialize)]
struct RunResult {
    lang: &'static str,
    tpm: u32,
    accuracy: f64,
}

#[tokio::main]
async fn main() -> Result<(), reqwest::Error> {
    let client = reqwest::Client::new();
    let payload = RunResult { lang: "rust", tpm: 104, accuracy: 97.5 };

    let response = client
        .post("https://typestar.io/api/results")
        .bearer_auth("token-goes-here")
        .header("X-Client", "typestar-cli")
        .json(&payload)
        .send()
        .await?;

    println!("{}", response.status());
    Ok(())
}

How it works

1. json sets the body and the content type together.
2. header adds one header; bearer_auth is the shorthand.
3. send is where the request actually goes out.
