Yes there was a pretty major change in crust (futures/tokio etc. will be getting added there). We will be providing more examples and in fact adding quite a bit to crust in the coming months (further NAT traversal, protocols, formalise the wire protocol etc.). @nbaksalyar will be working there soon and I cannot wait, he did a great job in writing up blog posts and code for a rust networking library. We are also looking to sub contract some parts as well. IT will be simpler again, I had a chat with another couple of project leads tonight, facilitated by @MrAnderson and said there I wanted crust to be seen as a truly useful for all projects networking library.
In the meantime if you are toying around and have examples we would love to see PR’s, the more the merrier there really.
Thanks though for poking around and reminding us of this as well.
