pub struct PyMiddlewares { /* private fields */ }
Expand description

Structure holding the list of Python middlewares that will be executed by this server.

Middlewares are executed one after each other inside the crate::PyMiddlewareLayer Tower layer.

Implementations

Create a new instance of PyMiddlewareHandlers from a list of heandlers.

Add a new handler to the list.

Execute all the available Python middlewares in order of registration.

Once the response is returned by the Python interpreter, different scenarios can happen:

  • Middleware not returning will let the execution continue to the next middleware without changing the original request.
  • Middleware returning a modified PyRequest will update the original request before continuing the execution of the next middleware.
  • Middleware returning a PyResponse will immediately terminate the request handling and return the response constructed from Python.
  • Middleware raising PyMiddlewareException will immediately terminate the request handling and return a protocol specific error, with the option of setting the HTTP return code.
  • Middleware raising any other exception will immediately terminate the request handling and return a protocol specific error, with HTTP status code 500.
