Struct rustc_hir::TraitItem

source ·
pub struct TraitItem<'hir> {
    pub ident: Ident,
    pub owner_id: OwnerId,
    pub generics: &'hir Generics<'hir>,
    pub kind: TraitItemKind<'hir>,
    pub span: Span,
    pub defaultness: Defaultness,
}
Expand description

Represents an item declaration within a trait declaration, possibly including a default implementation. A trait item is either required (meaning it doesn’t have an implementation, just a signature) or provided (meaning it has a default implementation).
