Struct FnMiddleware 

pub struct FnMiddleware<F> { /* private fields */ }

Function-based Middleware

Helper to create middleware from async functions without implementing the full Middleware trait.

Implementations

impl<F> FnMiddleware<F>

pub fn new(func: F) -> Arc<Self>

Creates a new function-based middleware.

Examples

use wsforge::prelude::*;

let middleware = FnMiddleware::new(|msg, conn, state, ext, mut next| async move {
    println!("Before handler");
    let response = next.run(msg, conn, state, ext).await?;
    println!("After handler");
    Ok(response)
});

Trait Implementations

impl<F, Fut> Middleware for FnMiddleware<F>

where F: Fn(Message, Connection, AppState, Extensions, Next) -> Fut + Send + Sync + 'static, Fut: Future<Output = Result<Option<Message>>> + Send + 'static,

fn handle<'life0, 'async_trait>( &'life0 self, message: Message, conn: Connection, state: AppState, extensions: Extensions, next: Next, ) -> Pin<Box<dyn Future<Output = Result<Option<Message>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Handle a message and optionally pass it to the next middleware.
