Support for compression

[avently]

Your app is cool, use it sometimes. Thank you!

Now it lacks a compression support.
Here is a link I found with comments about what is it and why: https://www.igvita.com/2013/11/27/configuring-and-optimizing-websocket-compression/

It's an old page but the info should be relevant I hope.

Can you add this permessage-deflate compression into websocat?
Only for client-side is enough.

Maybe, but probably not in short term.

The place where it needs to be added is rust-websocket library, which is not very actively maintained.

I hesitate between improving rust-websocket and migrating Websocat to a different WebSocket library...

Seems like tungstenite-rs has a WiP PR which is going to implement the required functionality:
snapview/tungstenite-rs#235

Would it make sense to swap rust-websocket to tungstenite-rs to have this feature implemented?

Future's Websocat v3 is indeed based on tokio-tungstenite and should gain compression support when tungstenite gains it.

But it is not feasible to make substantial changes to Websocat v1, which is based on pre-async/await Tokio 0.1. There is no specific schedule for releasing Websocat v3 either - it's unlikely to be this year. I can make a build of it for some specific use case that cannot be handled by Websocat v1 although if needed.

thx for your reply. good to know that v3 is in the making! I'll check it out sometime!
