You can have all this from here.

[apasel422]

@GuillaumeGomez Do you have more information on the code that causes this?

[GuillaumeGomez]

Code is kinda old but it seems to build just fine (by build I mean cargo doc runs normally).

[apasel422]

So can this be closed?

[GuillaumeGomez]

Absolutely.
