Trait MiddlewareContract 

pub trait MiddlewareContract: ConcreteMiddleware {
    // Required method
    fn handle<'life0, 'async_trait>(
        &'life0 self,
        request: Request,
        next: Next,
    ) -> Pin<Box<dyn Future<Output = Response> + Send + 'async_trait>>
       where 'life0: 'async_trait,
             Self: 'async_trait;

    // Provided method
    fn name(&self) -> &'static str { ... }
}

A stage in the request pipeline.

Required Methods

fn handle<'life0, 'async_trait>( &'life0 self, request: Request, next: Next, ) -> Pin<Box<dyn Future<Output = Response> + Send + 'async_trait>>

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

Handle the request, optionally calling next.

Returning without calling next.run(..) short-circuits the pipeline — the handler and every later middleware are skipped. That is how authentication, rate limiting and CORS preflight all work.

Provided Methods

fn name(&self) -> &'static str

A label for diagnostics and route:list.

Defaults to the type’s short name. This is a label, not an identifier: nothing looks middleware up by it, so two stages sharing one is untidy rather than broken.

Dyn Compatibility

This trait is dyn compatible.

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