class _MiddlewarePipeline: (source)
Constructor: _MiddlewarePipeline(instances, request, terminal, terminal_args)
Middleware pipeline with request-local execution state.
A single instance encapsulates the execution state for one middleware stack invocation. Each layer receives a fixed continuation so concurrent invocations cannot change the depth observed by another middleware.
| Async Method | __advance |
Invoke the layer at a fixed depth with its own continuation. |
| Async Method | __call__ |
Start the middleware stack once for this request. |
| Method | __init__ |
Store the middleware stack and terminal callable for one request. |
| Class Variable | __slots__ |

Invoke the layer at a fixed depth with its own continuation.
| Parameters | |
depth:int | Position of the middleware or terminal to execute. |
| Returns | |
T | Result returned by this middleware and its descendants. |
Start the middleware stack once for this request.
| Returns | |
T | Result produced by the middleware stack or terminal. |
| Raises | |
RuntimeError | If this pipeline has already started. |
