Trait HandlerMiddleware 

pub trait HandlerMiddleware<T: Send + Sync + 'static>:
    Send
    + Sync
    + 'static {
    // Required method
    fn wrap(
        &self,
        next: Arc<dyn MessageHandler<T>>,
    ) -> Arc<dyn MessageHandler<T>>;
}

Middleware that wraps a handler with cross-cutting concerns.

Each middleware receives the next handler in the chain and returns a new handler that adds behaviour around it (logging, metrics, error recovery, etc.).

Required Methods

fn wrap(&self, next: Arc<dyn MessageHandler<T>>) -> Arc<dyn MessageHandler<T>>

Wrap the given handler, returning a new handler that adds middleware behaviour.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
