Enum rustc_query_system::query::SimpleDefKind

pub enum SimpleDefKind {
    Struct,
    Enum,
    Union,
    Trait,
    TyAlias,
    TraitAlias,
    Other,
}

A simplified version of rustc_hir::def::DefKind.

It was added to help improve cycle errors caused by recursive type aliases. As of August 2021, rustc_query_system cannot depend on rustc_hir because it would create a dependency cycle. So, instead, a simplified version of DefKind was added to rustc_query_system.

DefKinds are converted to SimpleDefKinds in rustc_query_impl.
