Tweak binop errors * Suggest potentially missing binop trait bound (fix #73416) * Use structured suggestion for dereference in binop 2020-06-24 00:32:06 +00:00			`//@ run-rustfix`
Detect double reference when applying binary op ```rust let vr = v.iter().filter(\|x\| { x % 2 == 0 }); ``` will now yield the following compiler output: ```bash ERROR binary operation `%` cannot be applied to type `&&_` NOTE this is a reference of a reference to a type that `%` can be applied to, you need to dereference this variable once for this operation to work NOTE an implementation of `std::ops::Rem` might be missing for `&&_` ``` The first NOTE is new.
