A trait's definition with type information.

Fields

If true, then this trait had the #[rustc_paren_sugar] attribute, indicating that it should be used with Foo() sugar. This is a temporary thing -- eventually any trait will be usable with the sugar (or without it).

has_auto_impl: bool

The ICH of this trait's DefPath, cached here so it doesn't have to be recomputed all the time.
