Required Methods

fn suggest_item_with_attr<D: Display + ?Sized>(&mut self,
                                               cx: &T,
                                               item: Span,
                                               msg: &str,
                                               attr: &D)

Suggests to add an attribute to an item.

Correctly handles indentation of the attribute and item.

Example

db.suggest_item_with_attr(cx, item, "#[derive(Default)]");

fn suggest_prepend_item(&mut self,
                        cx: &T,
                        item: Span,
                        msg: &str,
                        new_item: &str)

Suggest to add an item before another.

The item should not be indented (expect for inner indentation).

Example

db.suggest_prepend_item(cx, item,
"fn foo() {
    bar();
}");
