Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @alexcrichton (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

The default is 2015. Perhaps there is some confusion because cargo new auto-populates it with the latest edition?

@ehuss So if I am understanding this correctly, If I don't add the "edition" label in the Cargo.toml file it will be set to '2015' by default and if I use cargo new/init without any flags it would add the '2018' label itself?

[ehuss]

Correct.
