Description
Raising this now so that we can decide what the plan is here.
- Document editions
- Make sure that all examples are using Rust 2018 compatible code (paths are the main concern).
- How do editions interact with mdbook test?
- Documenting Rust 2015 differences (assuming that the reference moves to Rust 2018 by default)
- Should these be inline, or in an appendix.
