The foreign links docs mention: So for the example above all errors deriving from the temp::Error... but there are no code examples of foreign_links(the first code example contains an example of foreign_links usage) above that text and also no docs containing temp.

Oops. Do you want to do a PR?

I'll pass because you guys know better what kind of code examples you could give + I am new to the crate.

It would be an occasion to understand it better ^^
