How to use websocket client?

Hello !

I'm using websocket crate since the start of my project, like this (see source code here) by using reader and writer in separated threads:

[dependencies]
websocket = "0.24.0"
use websocket::ClientBuilder;

fn main() {
    let (mut ws_reader, mut ws_writer) = ClientBuilder::new("ws://echo.websocket.org")
        .unwrap()
        .connect_insecure()
        .unwrap()
        .split()
        .unwrap();
   
   // use ws_reader in a thread, and ws_writer in an other thread
}

I am now implementing SSL on my server. So I use connect instead of connect_insecure, like this:

use websocket::ClientBuilder;

fn main() {
    let (mut ws_reader, mut ws_writer) = ClientBuilder::new("ws://echo.websocket.org")
        .unwrap()
        .connect(None)
        .unwrap()
        .split()
        .unwrap();

   // use ws_reader in a thread, and ws_writer in an other thread
}

But, there is no split method on websocket::sync::Client<Box<dyn NetworkStream + std::marker::Send>>:

error[E0599]: no method named `split` found for struct `websocket::sync::Client<Box<dyn NetworkStream + std::marker::Send>>` in the current scope

    |
    = note: the method `split` exists but the following trait bounds were not satisfied:
            `Box<dyn NetworkStream + std::marker::Send>: Splittable`
            `<Box<dyn NetworkStream + std::marker::Send> as Splittable>::Reader = _`
            `<Box<dyn NetworkStream + std::marker::Send> as Splittable>::Writer = _`

Documentation only show .split usage with connect_insecure. I do not understand how i can have my reader/writer by using .connect method.

Help would be very appreciated ... :slight_smile:

I've only quickly skimmed your post, but everyone I've helped so far has had a lot better success with the tungstenite crate (or tokio-tungstenite for async) when using websockets.

Hello @alice , i will take a look about this create, thanks.
