What would be the smallest setting with tokio?

[bamthomas]

Thanks for the library. I'm using it with others for a load injector. I'm depending already on tokio.

I have this compilation error:

error[E0277]: the trait bound `tokio::net::TcpStream: futures_io::if_std::AsyncRead` is not satisfied
  --> src/imap_client.rs:6:13
   |
6  |     client: Client<TlsStream<TcpStream>>,
   |             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ the trait `futures_io::if_std::AsyncRead` is not implemented for `tokio::net::TcpStream`

I have reproduced a similar compilation issue with the example: I removed optional features and set tokio as configured in my project (that includes same features from tokio i.e. rt-multi-thtread and macros). So I came with the following Cargo.toml:

[package]
name = "async-imap-examples"
version = "0.1.0"
publish = false
authors = ["dignifiedquire <me@dignifiedquire.com>"]
license = "Apache-2.0/MIT"
edition = "2018"


[dependencies]
anyhow = "1"
async-imap = { path = "../", features = [ "tokio" ]  }
async-native-tls = { version = "0.5", features = [ "tokio" ] }
futures = "0.3.28"
tokio = { version = "1.32", features = ["net", "io-util", "time", "rt", "rt-multi-thread", "macros"] }

And the headers from the idle file:

use std::env;
use std::time::Duration;

use anyhow::{bail, Result};
use async_imap::extensions::idle::IdleResponse::*;
use futures::StreamExt;

use tokio::{net::TcpStream, task, time::sleep};

#[tokio::main]
async fn main() -> Result<()> {
    // ...
}
// ...

What is missing or is misconfigured in this file?
(sorry if it's a dumb question, I'm not a rust advanced user yet)

async-native-tls feature is named runtime-tokio, not tokio.

Should be like this:

async-native-tls = { version = "0.5", features = [ "runtime-tokio" ] }

[bamthomas]

thank you for your answer @link2xt but when I use runtime-tokio I have

Even if I use tokio 1.0.
Do I need to import async-native-tls in a specific way?

[link2xt]

You also need to disable default runtime-async-std:

async-native-tls = { version = "0.5", default-features = false, features = ["runtime-tokio"] }

async-native-tls still enables async-std runtime by default for backwards compatibility.

[bamthomas]

Yay !!
It works. Thank you for your patience.

If this can help, I ended up with :

[dependencies]
anyhow = "1"
async-imap = { path = "../", default-features = false, features = [ "tokio", "runtime-tokio" ] }
async-native-tls = { version = "0.5", default-features = false, features = [ "runtime-tokio" ] }
futures = "0.3.28"
tokio = { version = "1.32", features = ["net", "io-util", "time", "rt", "rt-multi-thread", "macros"] }

Bruno, if you feel like opening a little documentation PR that would be useful i think.
