Inclusive wildcard (prefix/{*route}) that matches prefix/ and prefix/* without duplicating routes

Summary

I'm struggling to make a catchall route work on Axum 0.8, since the wildcard doesn't match an empty string. The easy way out of this would be to duplicate the route (one for prefix/, one for prefix/{*rest}), but I'm using utoipa for openapi generation and this approach leads to duplicate routes in the generated openapi document. Anyone know of a workaround for this?

For context, I've built a Git service and am trying to build out the HTTP api for accessing files in a way that is compatible with Github's contents API (both /owner/repo/contents/path/to/file.txt and /owner/repo/contents need to work).

axum version

0.8.1

When I ran into this, I just created the two routes.

I don't think there's a workaround right now, this is based on the underlying matchit crate which doesn't allow empty captures if I recall correctly.

Ah, I see. Thanks for the info! I'll see if I can just exclude one of the routes from utoipa's route capturing instead of trying to avoid duplicating the routes.
