Ce que l'on suppose souvent
Calling Service::call borrows &mut self for the entire lifetime of the returned Future, preventing a single unbuffered service instance from polling and dispatching subsequent requests while a prior request is in flight.
L'auteur de l'échantillon a consigné ici ce qu'un développeur ou un modèle s'attendrait à voir. Le contrat ci-dessous est ce qui s'est réellement exécuté.
Contrat
- Passing a mutable reference &mut S into a generic Service consumer yields S::Future without tying the future to the &mut borrow lifetime, allowing immediate re-borrowing to poll and dispatch subsequent requests while earlier futures remain in flight
- Box<dyn Service<Request, Response = Res, Error = Err, Future = Fut>> implements Service directly via blanket impl, requiring the Future associated type to be explicitly defined for trait object safety
- Each poll_ready readiness permit is single-use and consumed by the subsequent call, delegating transparently through &mut S and Box<S> blanket implementations
