Example of a Rust binary that utilizes async/await

[ducaale]

None of the examples I found so far was using async/await

• https://github.com/wapm-packages/rust-wasi-example
• https://github.com/wapm-packages/qr2text

My goal is to compile reqwest which supports WASM to WASI.

// reqwest = { version = "0.11", features = ["json"] }
// tokio = { version = "1", features = ["full"] }
use std::collections::HashMap;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let resp = reqwest::get("https://httpbin.org/ip")
        .await?
        .json::<HashMap<String, String>>()
        .await?;
    println!("{:#?}", resp);
    Ok(())
}

This currently fails because mio doesn't currently support WASI. Is there something I could replace tokio to make this work?
