Enum rustc_ast::ast::AttrKind

source · [−]

pub enum AttrKind {
    Normal(P<NormalAttr>),
    DocComment(CommentKind, Symbol),
}

Variants

`Normal(P<NormalAttr>)`

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).

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.
