How to access `operation_id` in middleware?

[banool]

Hey, I have some logging middleware where I'd love to do log based on operation_id, but I don't know how I can access that data from middleware. I can't see anything on request or next that lets me access this information about the endpoint.

Thanks!

I'll add it tomorrow.

When I thought about it, I found that this is not easy to achieve, the outer middleware cannot get the operation_id. 😂

I see, I wonder if there is some way I can pass it in manually per route then into some middleware? Or get the function name of the handler instead?

Currently I'm using the path but that is a breaking change compared to our previous warp based method.

I've add an example to show how to get the operation-id from the response.

omg you're such a legend, thanks so much for this, looks like it'll work great. I'll try it out soon, probably on the next poem-openapi release to crates.io, or maybe before that if I get time. Thanks again!!

Used it here: https://github.com/aptos-labs/aptos-core/pull/2781! Still testing but looks good!
