Struct TypeHierarchyServiceHandle 

pub struct TypeHierarchyServiceHandle { /* private fields */ }

Cloneable, type-erased type-hierarchy service registered by an adapter.

A handle may hold several services over disjoint sources, as a federated session does; each question goes to the service covering the source.

Implementations

impl TypeHierarchyServiceHandle

pub fn new(service: Arc<dyn TypeHierarchyService>) -> Self

Wraps a trusted hierarchy service.

pub fn is_a( &self, source: &SourceId, kind: &str, ancestor: &str, ) -> Result<bool, TypeHierarchyError>

Answers for one object’s source, refusing sources the service does not cover.
