Enum rustc_ast::ast::AttrKind

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

Variants

Normal(AttrItem, Option<LazyTokenStream>)

A normal attribute.

Tuple Fields of Normal

0: AttrItem1: Option<LazyTokenStream>

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).

Tuple Fields of DocComment

0: CommentKind1: Symbol

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
