See that `edition = "2018"`? That's what opts you in to the new features.
Set it, `cargo +beta build`, and you should be good to go!

## Writing idiomatic code

We have some new lints that suggest using certain idioms in your Rust 2018
code. We don't have them turned on by default yet. To see what your code would
look like, you can use `cargo fix`:

```console
$ cargo +beta fix --edition-idioms
```

If things look great, or things look terrible, please let us know! We hope to make
these lints warn by default after gaining some experience with them and working
out the bugs.

> The `--edition-idioms` flag applies only to the "current crate"; if you want
> to run it against a workspace is necessary to use a workaround with `RUSTFLAGS`
> in order to execute it in all the workspace members.
>
> $ RUSTFLAGS='-Wrust_2018_idioms' cargo fix --all
