AfterMiddleware are fired after a Handler is called inside of the Middlewares chain.

AfterMiddleware receive both a Request and a Response and are responsible for doing any response post-processing.

AfterMiddleware should not overwrite the contents of a Response. In the common case, a complete response is generated by the Middlewares’s Handler and AfterMiddleware simply do post-processing of that Response, such as adding headers or logging.

Provided Methods

fn after<'life0, 'life1, 'async_trait>( &'life0 self, _: &'life1 mut Request, res: Response, ) -> Pin<Box<dyn Future<Output = Result<Response>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Do whatever post-processing this middleware should do.

fn catch<'life0, 'life1, 'async_trait>( &'life0 self, _: &'life1 mut Request, err: Error, ) -> Pin<Box<dyn Future<Output = Result<Response>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Respond to an error thrown by previous AfterMiddleware or the Handler.

Returning Ok will cause the request to resume the normal flow at the next AfterMiddleware.
