Cookies and GET in axum

help
1

I am writing an example for a template system (neutralts) in axum, the thing is that I have never used axum and I get a lot of errors when I try to read get parameters and cookies. the example is simply this:

async fn home_handler() -> Response<String> {
 ..
}

async fn handle_404() -> Response<String> {
     ...
}

#[tokio::main]
async fn main() {
    let app = Router::new()
        .route("/", get(home_handler))
        .fallback(handle_404);

    let addr = ([127, 0, 0, 1], 9090).into();
    axum::Server::bind(&addr)
        .serve(app.into_make_service())
        .await
        .unwrap();
}

Can someone help me to make home_handler able to read cookies and get variables? I could use a link with examples about this.

There is the tower-cookies crate which you can use to do cookie management in axum. It has examples.

To clarify, every time I add parameters to home_handler, I get this error:

the trait bound `fn({type error}) -> impl Future<Output = &'static str> {handler}: Handler<_, _>` is not satisfied
   --> src/main.rs:8:25
    |
8   |         .route("/", get(home_handler))
    |                     --- ^^^^^^^ the trait `Handler<_, _>` is not implemented for fn item `fn({type error}) -> impl Future<Output = &'static str> {handler}`
    |                     |
    |                     required by a bound introduced by this call

The parameters of your handler must be extractors. I suspect {type error} doesn't implement FromRequest or FromRequestParts, so it doesn't qualify as extractor.

I think I'm going to give up because I have a lot of web fw to do examples and it's consuming me a lot of time this one, I appreciate the answers, anyway if anyone can help me with this I'll be grateful here are the examples:

Thanks
