This is a first step in order to complete this issue: #29370
I submitted this PR with the help of @steveklabnik More info here: #29370 (comment)

It's my first PR on Rust, I'm learning how to contribute: Should I ping someone? I will post another PR with a more complicated example soon, I prefer send it separately (cause maybe I made some mistakes).

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @brson (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 Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed.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.

Should I ping someone?

Nope, as you can see, @rust-highfive has your back 😄 that said, let's assign this to me, not brian:

r? @steveklabnik

I will post another PR with a more complicated example soon, I prefer send it separately (cause maybe I made some mistakes).

[steveklabnik]

could you add another /// above this line, please?

[rap2hpoutre]

Ok I updated

[rap2hpoutre]

Thanks for all the time you spent to help me!

[steveklabnik]

No problem! Very glad to do so.

[steveklabnik]

Looks great, thanks! Travis found an issue though:

https://travis-ci.org/rust-lang/rust/jobs/216364459#L564-L566

these three lines have trailing whitespace. Can you remove them?

[rap2hpoutre]

Fixed. Thanks again!

@steveklabnik Travis fails again but I don't understand why what I have done make it crash. Reading the log does not help me: https://api.travis-ci.org/jobs/216373325/log.txt?deansi=true

It ends with:

$ cat obj/tmp/sccache.log
cat: obj/tmp/sccache.log: No such file or directory

$ cat /tmp/sccache.log
cat: /tmp/sccache.log: No such file or directory

$ ls $HOME/Library/Logs/DiagnosticReports/
ls: cannot access /home/travis/Library/Logs/DiagnosticReports/: No such file or directory

$ dmesg | grep -i kill
[   14.352873] init: failsafe main process (1136) killed by TERM signal


Done. Your build exited with 1.

[steveklabnik]

Looks like a spurious failure; I'm going to retry it.

This needs to be changed to ```no_run so it doesn't try to run this code as a test.

[rap2hpoutre]

Ok thanks, done!

[rap2hpoutre]

@steveklabnik It passes now :)
