Struct rustc_hir::hir::TraitItem

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,
}

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).

Fields

ident: Ident

owner_id: OwnerId

generics: &'hir Generics<'hir>

kind: TraitItemKind<'hir>

span: Span

defaultness: Defaultness

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.
