Struct rustc_hir::hir::TraitItem

pub struct TraitItem<'hir> {
    pub ident: Ident,
    pub owner_id: OwnerId,

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).
