Hi, you need to update your compiler it seems (it seems that you do not have the full Rust 2018 compiler). A lot of streamlining and ease of use was added in the release after Rust 2018, which I based most on. This is what give the nice readability :) Build fine for me on stable rustc 1.34.2 (6c2484dc3 2019-05-13).

Run rustup update

I have tested and you only need to update one minor version to rust version 1.32.0 (9fda7c223 2019-01-16) to have it all working. So you do not need to go to the latest, only the full Rust 2018.
