roa-tokio boot failed

[you06]

I tried this case and got failed.

use roa::{App, Context};
use roa_tokio::{TcpIncoming, Exec};
use std::error::Error;

async fn end(_ctx: &mut Context) -> roa::Result {
    Ok(())
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {
    let app = App::with_exec((), Exec).end(end);
    let incoming = TcpIncoming::bind("127.0.0.1:0")?;
    println!("server is listening on {}", incoming.local_addr());
    app.accept(incoming).await?;
    Ok(())
}

Dependencies.

roa = "0.5.3"
roa-tokio = "0.5.1"
tokio = {version = "1.13", features = ["full"]}

Ok, I see that roa-tokio@0.5.1 uses the out-of-date tokio. Use the version in the master branch, it's fine now.

The v0.6 is ready for release (only the roa-tokio is in the alpha stage).

[Hexilee]

The v0.6 is released. In this version, tokio is the default runtime and network provider. Please just use roa instead of roa-tokio. @you06
