gen: middleware support

[screwyprof]

Description

At the moment the project uses a custom static router which doesn’t support middleware.

It would be great if it was possible to add support for different types of middleware:

1. middleware which runs for all requests
2. middleware that runs per endpoint

We have ogen/middleware (that is 1) and (2) looks like #566

Thanks for the quick response.

Also, you could use Server.FindRoute method (2).

Would be great to have more information exposed (entire Route struct) inside the middleware context.

I came across a situation where I have a external module implementing the middleware that need the Route.pathPattern field. In that situation I can't use (1) because the Request struct doesn't have the needed field and (2) does not work because i can't/doesn't want to import generated code to be able to call FindRoute

Any ideas ?

We have ogen/middleware

How to add those middlewares? Docs has zero information about it. Ok, we have created func Logging(logger *zap.Logger) middleware.Middleware {...} then what? How it would be in execution chain?
