Trait NgynMiddleware 

pub trait NgynMiddleware: Send + Sync {
    // Required method
    fn handle(cx: &mut NgynContext<'_>) -> impl Future<Output = ()> + Send
       where Self: Sized;
}

Trait for implementing a middleware.

Middlewares are how Ngyn processes requests. They can be used to modify the request context, the response, or both.

A few things to note about middlewares:

• They are executed in the order they are added.
• They can be used to modify the request context, the response, or both.
• They can be used to short-circuit the request handling process.
• They are purely synchronous and should not ideally not have side effects.

Examples

pub struct RequestReceivedLogger {}

impl NgynMiddleware for RequestReceivedLogger {
  async fn handle(cx: &mut NgynContext<'_>) {
   println!("Request received: {:?}", cx.request());
 }
}

Required Methods

fn handle(cx: &mut NgynContext<'_>) -> impl Future<Output = ()> + Send

where Self: Sized,

Handles the request.
