Bumped dependency versions

[pranav-bhatt]

The main motivation behind this was that thetokio version being used in this crate was still 0.2 and this was causing major issues in my project. Refactored it to use tokio 1.7*, and also ran cargo fmt (Do tell me if this might cause issues).

I also wanted to ask if this warrants a version bump since the change in tokio versions might cause issues for others.

Some of the tests failed, not sure why :/ :

EDIT:
I apologise for not being clear enough. I not sure why the payload is being modified

[Covertness]

It seems the payload was changed

[pranav-bhatt]

It seems the payload was changed

@Covertness So it seems the response that is being received is the one from the response_handler, i.e, b"OK". I'm not even sure how in the original repo this test case was passing. Shouldn't the client.receive() be getting "OK" as the response always in the original code?

Would you be able to take a look? Hopefully shouldn't take too long :)

The problem happened on this line. The socket always produce Poll::Ready result after the first frame reached. It maybe caused by the new version of tokio_util::udp::UdpFramed

Are you a part of an IRC or Slack server so I could ping you there?

I'll try downgrading this and check.

Downgrading to a version below 0.6 unfortunately breaks stuff. Guess we'll have to figure out another way.

[Covertness]

The new version has its own Stream. I think it will be compatible with the socket of new version.

The new version has its own Stream. I think it will be compatible with the socket of new version.

Do correct me if I'm wrong, but from what I can see, the Stream trait is just a reexport of the futures::stream::Stream trait, so I don't think this is the issue. Quoting tokio_stream::StreamExt:

Be aware that the Stream trait in Tokio is a re-export of the trait found in the futures crate, however both Tokio and futures provide separate StreamExt utility traits, and some utilities are only available on one of these traits. Click here to see the other StreamExt trait in the futures crate.

If you need utilities from both StreamExt traits, you should prefer to import one of them, and use the other through the fully qualified call syntax.

The necessary functions like poll_next_unpin() are imported from futures::StreamExt, so from what I can see, tokio_stream::StreamExt is also not necessary.

I've also started a discussion here in the tokio repo :)

[Covertness]

Okay. Waiting for the reply from the tokio team.

Okay. Waiting for the reply from the tokio team.

@Covertness I had a couple of other issues, and I was hoping that we could communicate real-time over a chat service. Could I possibly have your slack or twitter handle (or any other chat service that suits you)? My email ID is adpranavb2000@gmail.com

[pranav-bhatt]

Can we have a new release? v1.0 wink wink

[Covertness]

Sorry for not getting back to you sooner. So busy recently. You can touch me by email if you want communicate with me. My email is wuyingfengsui@gmail.com.
Thank you for your pr. I will release it.
