Struct SchemaGraphProvider 

pub struct SchemaGraphProvider { /* private fields */ }

Synthetic graph computed live from a SchemaSource. Cheap to construct; each call snapshots the catalog (the server already caches schema reads).

Implementations

impl SchemaGraphProvider

pub fn new(source: Arc<dyn SchemaSource>) -> Self

Trait Implementations

impl GraphProvider for SchemaGraphProvider

fn overview<'life0, 'life1, 'async_trait>( &'life0 self, realm: Option<&'life1 str>, limit: usize, ) -> Pin<Box<dyn Future<Output = Result<GraphPayload>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Capped sample of the whole graph: stats + nodes + edges.

fn node<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<GraphNode>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

A single node by id, or None if absent.

fn neighbors<'life0, 'life1, 'async_trait>( &'life0 self, ids: &'life1 [String], dir: Direction, _only_internal: bool, limit: usize, ) -> Pin<Box<dyn Future<Output = Result<EdgeExpansion>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Edges touching ids (respecting dir), plus the node ids newly reached.

fn subgraph<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 str, depth: usize, ) -> Pin<Box<dyn Future<Output = Result<GraphPayload>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

BFS from id up to depth hops (both directions); returns the subgraph.

fn search<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, text: &'life1 str, labels: &'life2 [String], realm: Option<&'life3 str>, limit: usize, offset: usize, ) -> Pin<Box<dyn Future<Output = Result<SearchHits>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Nodes whose name matches text (case-insensitive), optionally filtered by labels / realm.

fn stats<'life0, 'life1, 'async_trait>( &'life0 self, realm: Option<&'life1 str>, ) -> Pin<Box<dyn Future<Output = Result<GraphStats>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Node and relationship counts, optionally scoped to a single realm.

fn schema<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<GraphSchema>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Structural summary: known node kinds, edge types, and property keys per kind.
