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

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).
