Could you please tell me about the context of the extension?

[myyrakle]

For example I

1. Database connection object
2. Authentication-related values ​​of the current request

I want to manage the above two as state values.

Number 1 is a DB setting for all handlers or middleware to share and use.
Number 2 is to read the authorization in the middleware and pass the authorization result to the handler.

In my opinion, number 1 should be server-wide state sharing, and number 2 should be state sharing specific to a specific request.

Can axum Extension manage these two separately? What are the default settings?

Can axum Extension manage these two separately?

Yes. Do router.layer(Extension(db)) for the global and from your auth middleware do request.extensions_mut().insert(...).
