Struct rustc_hir::hir::ForeignItemRef

pub struct ForeignItemRef {
    pub id: ForeignItemId,
    pub ident: Ident,
    pub span: Span,
}

A reference from a foreign block to one of its 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: ForeignItemId

ident: Ident

span: Span

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.
