Vary middleware

[imbolc]

Here's how it looks (just a draft yet). Let me know if you're ok with the approach before I finish it.

Also I've noticed you implemented tower middleware in the guard, is there any benefits compared to axum::middleware::from_fn. I can't imagine how one would use the crate without axum, so depending on it instead of axum-core seems ok, isn't it?

@robertwayne haven't had a chance to look at it yet?

[robertwayne]

Woops, sorry about that - it got lost in my sea of notifications. I'll look over this later today!

[imbolc]

Sure, no hurry :)

[robertwayne]

Yeah, I'm good with this approach. It's about what I envisioned when you originally brought up channels. You can finish This should live behind a feature, for sure.

Yeah, it certainly could have used the axum from_fn method. I just chose to go with the most flexible (and lowest level) option available after initially reading through the axum middleware documentation.

@robertwayne just making sure you don't miss it, no hurry

Thanks for the ping (and the work on this)!

This looks great to me; tests, docs, and example. Thank you again!
