First of all, I have to say this This book is ABSOLUTELY AMAZING!. Congrats for this amazing work Denis!

Is there any plan to make a Second Edition updating it to async/await syntax now that is a stable rust feature?

Thanks!

Hello,

thank you for the wonder book. I was hoping that you can update chapter 6 code. Currently the jsonrpc examople doesn't work. I get the following message for the compiler:

error[E0107]: wrong number of type arguments: expected 1, found 0
  --> src/main.rs:19:13

Thanks
