Enum rustc_ast::ast::AttrKind

source · [−]

pub enum AttrKind {
    Normal(AttrItem, Option<LazyTokenStream>),
    DocComment(CommentKind, Symbol),
}

Variants

`Normal(AttrItem, Option<LazyTokenStream>)`

A normal attribute.

`DocComment(CommentKind, Symbol)`

A doc comment (e.g. /// ..., //! ..., /** ... */, /*! ... */). Doc attributes (e.g. #[doc="..."]) are represented with the Normal variant (which is much less compact and thus more expensive).
