Fields

span: Span

🔬 This is a nightly-only experimental API. (rustc_private)

The span for the current #[derive(Foo)] header.

attributes: Vec<Attribute>

🔬 This is a nightly-only experimental API. (rustc_private)

path: Path<'a>

🔬 This is a nightly-only experimental API. (rustc_private)

Path of the trait, including any type parameters

additional_bounds: Vec<Ty<'a>>

🔬 This is a nightly-only experimental API. (rustc_private)

Additional bounds required of any type parameters of the type, other than the current trait

generics: LifetimeBounds<'a>

🔬 This is a nightly-only experimental API. (rustc_private)

Any extra lifetimes and/or bounds, e.g. D: serialize::Decoder

is_unsafe: bool

🔬 This is a nightly-only experimental API. (rustc_private)

Is it an unsafe trait?

supports_unions: bool
