Disambiguators

rustc_ast_lowering::item

Enum Disambiguators 

Source 
pub(crate) enum Disambiguators {
    Default(LocalDefIdMap<PerParentDisambiguatorState>),
    Delayed(Arc<LocalDefIdMap<Steal<PerParentDisambiguatorState>>>),
}
Expand description

Default disambiguators are used during default lowering, when we lower AST owners in a loop we can use the whole map, in contrast delayed lowering lowers each AST owner separately, so we use readonly disambiguators map with Steals to get disambiguators.
