Trait Implementations

impl<'vertex, AdapterT> Adapter<'vertex> for AdapterTap<'vertex, AdapterT>where AdapterT: Adapter<'vertex>, for<'de2> AdapterT::Vertex: Clone + Debug + PartialEq + Eq + Serialize + 'vertex + Deserialize<'de2>,

type Vertex = <AdapterT as Adapter<'vertex>>::Vertex

The type of vertices in the dataset this adapter queries. It’s frequently a good idea to use an Rc<…> type for cheaper cloning here.

fn resolve_starting_vertices( &self, edge_name: &Arc<str>, parameters: &EdgeParameters, resolve_info: &ResolveInfo ) -> VertexIterator<'vertex, Self::Vertex>

Produce an iterator of vertices for the specified starting edge.

fn resolve_property( &self, contexts: ContextIterator<'vertex, Self::Vertex>, type_name: &Arc<str>, property_name: &Arc<str>, resolve_info: &ResolveInfo ) -> ContextOutcomeIterator<'vertex, Self::Vertex, FieldValue>

Resolve the value of a vertex property over an iterator of query contexts.

fn resolve_neighbors( &self, contexts: ContextIterator<'vertex, Self::Vertex>, type_name: &Arc<str>, edge_name: &Arc<str>, parameters: &EdgeParameters, resolve_info: &ResolveEdgeInfo ) -> ContextOutcomeIterator<'vertex, Self::Vertex, VertexIterator<'vertex, Self::Vertex>>

Resolve the neighboring vertices across an edge, for each query context in an iterator.

fn resolve_coercion( &self, contexts: ContextIterator<'vertex, Self::Vertex>, type_name: &Arc<str>, coerce_to_type: &Arc<str>, resolve_info: &ResolveInfo ) -> ContextOutcomeIterator<'vertex, Self::Vertex, bool>

Attempt to coerce vertices to a subtype, over an iterator of query contexts.

impl<'vertex, AdapterT> Clone for AdapterTap<'vertex, AdapterT>where AdapterT: Adapter<'vertex> + Clone, for<'de2> AdapterT::Vertex: Clone + Debug + PartialEq + Eq + Serialize + 'vertex + Deserialize<'de2> + Clone,

fn clone(&self) -> AdapterTap<'vertex, AdapterT>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'vertex, AdapterT> Debug for AdapterTap<'vertex, AdapterT>where AdapterT: Adapter<'vertex> + Debug, for<'de2> AdapterT::Vertex: Clone + Debug + PartialEq + Eq + Serialize + 'vertex + Deserialize<'de2> + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
