Required Methods

fn capabilities(&self) -> EngineCapabilities

fn cursor<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, ctx: &'life1 StoreCtx<'life2>, ) -> Pin<Box<dyn Future<Output = Result<EngineCursor, GraphEngineError>> + Send + 'async_trait>>

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

fn expand<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, ctx: &'life1 StoreCtx<'life2>, req: ExpandRequest, ) -> Pin<Box<dyn Future<Output = Result<ExpandResponse, GraphEngineError>> + Send + 'async_trait>>

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

Directed one-hop expansion of an authorized frontier. Chained by the caller with per-hop dedup; the engine never expands beyond one hop, so budgets and authorization are re-evaluated between hops rather than inside an opaque traversal.

fn shortest_path<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, ctx: &'life1 StoreCtx<'life2>, req: ShortestPathRequest, ) -> Pin<Box<dyn Future<Output = Result<PathResponse, GraphEngineError>> + Send + 'async_trait>>

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

Declared capabilities only; otherwise GraphEngineError::Unsupported.

fn match_pattern<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, ctx: &'life1 StoreCtx<'life2>, req: PatternRequest, ) -> Pin<Box<dyn Future<Output = Result<PatternResponse, GraphEngineError>> + Send + 'async_trait>>

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

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
