Update remaining examples to axum 0.7

[davidpdrsn]

This tracks the examples that haven't yet been updated to axum 0.7:

• rest-grpc-multiplex - Blocked. Requires tonic supporting http 1.0 (Upgrade to http 1.0 and axum 0.7 hyperium/tonic#1579)
• tls-graceful-shutdown - If we're using axum_server then its blocked but maybe it can be done using hyper directly. Not sure.
• tls-rustls - Blocked. Requires updating axum_server.
• reqwest-response
• http-proxy - Good to go, no blockers.
• reverse-proxy - No blockers. Can use hyper-util's legacy client.
• low-level-rustls - Fairly certain this one is good to go.
• low-level-openssl - Fairly certain this one is good to go.
• listen-multiple-addrs - Good to go, no blockers (claimed by @davidpdrsn)
• testing - No blockers. Can use hyper-util's legacy client (claimed by @davidpdrsn)
• unix-domain-socket - No blockers. Should be very similar to serve-with-hyper (claimed by @davidpdrsn)

Hi David, I'll have some time the next couple of weeks and would like to help with this one, if possible.

Cheers

Go ahead! Just post here which example you’re working on so others know.

I'll fix rest-grpc-multiplex example until tonic support http 1.0.

@takkuumi what do you mean? The example can't be updated yet.

@takkuumi what do you mean? The example can't be updated yet.

Not this mean, I’d wrote this example and I think that i can help on it.

[davidpdrsn]

I'm pretty sure the example can't be updated yet because tonic uses http 0.2 and axum now requires http 1.0. You can't convert requests/responses from 0.2 to 1.0 because extensions are totally opaque. Having to put a bunch of conversion code in an example isn't appropriate either.

I think people using axum with tonic will have to wait until tonic has been updated.

It looks like the tls-graceful-shutdown example is missing from this list.

axum 0.7 is really a big breaking

Thanks. Working on http-proxy first.

Will update here. Cheers.
