Where clauses

[silvioprog]

Hi.

Many parts in the Rust documentation shows where clause in front the user type and preserves the left brace in the same line of the fn keyword, e.g:

impl<T> PrintInOption for T where
    Option<T>: Debug {
    fn print_in_option(self) {
        println!("{:?}", Some(self));
    }
}

however, when we format those codes using rustfmt, they looks like this:

impl<T> PrintInOption for T
where
    Option<T>: Debug,
{
    fn print_in_option(self) {
        println!("{:?}", Some(self));
    }
}

Another example. Before formatting:

impl <A, D> MyTrait<A, D> for YourType where
    A: TraitB + TraitC,
    D: TraitE + TraitF {}

After formatting:

impl<A, D> MyTrait<A, D> for YourType
where
    A: TraitB + TraitC,
    D: TraitE + TraitF,
{
}

Notice the where and braces (wrong?) indentation.

I'm not sure if it is by design, so I decided to report that.

Thank you!

P.S.: All code examples was extracted from the official Rust online documentation.

thanks @silvioprog

Are you referring to the Book? If so, I believe that's because they aren't running rustfmt on all the code snippets and examples used there (rust-lang/book#1690 rust-lang/book#2008)

@silvioprog This is intentional. As @calebcartwright noted, all the rust code is not formatted by rustfmt yet. Thanks for the report!

Thanks guys. Up-vote for auto-formatting all documentation examples! 😃 👍
