Struct rustc_hir::ImplItemRef

pub struct ImplItemRef {
    pub id: ImplItemId,
    pub ident: Ident,
    pub kind: AssocItemKind,
    pub span: Span,
    pub trait_item_def_id: Option<DefId>,
}

A reference from an impl to one of its associated items. This contains the item’s ID, naturally, but also the item’s name and some other high-level details (like whether it is an associated type or method, and whether it is public). This allows other passes to find the impl they want without loading the ID (which means fewer edges in the incremental compilation graph).

Fields

id: ImplItemId

ident: Ident

kind: AssocItemKind

span: Span

trait_item_def_id: Option<DefId>

When we are in a trait impl, link to the trait-item’s id.

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.
