Trait ConnectMiddleware

pub trait ConnectMiddleware<A: Adapter, T>:
    Sized
    + Clone
    + Send
    + Sync
    + 'static {
    // Required method
    fn call<'a>(
        &'a self,
        s: Arc<Socket<A>>,
        auth: &'a Option<Value>,
    ) -> impl Future<Output = Result<(), Box<dyn Display + Send>>> + Send;
}

Define a middleware for the connect event. It is implemented for closures with up to 16 arguments. They must implement the FromConnectParts trait and return Result<(), E> where E: Display.

• See the connect module doc for more details on connect middlewares.
• See the extract module doc for more details on available extractors.

Required Methods

fn call<'a>( &'a self, s: Arc<Socket<A>>, auth: &'a Option<Value>, ) -> impl Future<Output = Result<(), Box<dyn Display + Send>>> + Send

Call the middleware with the given arguments.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
