Expand description

Raw persistence interface for task graphs.

All graph data is stored as a JSON blob. The orchestration layer in zeph-core is responsible for serializing/deserializing TaskGraph.

Required Methods§

Source

async fn save_graph( &self, id: &str, goal: &str, status: &str, graph_json: &str, created_at: &str, finished_at: Option<&str>, ) -> Result<(), MemoryError>

Persist a graph (upsert by id).

§Errors

Returns a MemoryError on database failure.

Source

async fn load_graph(&self, id: &str) -> Result<Option<String>, MemoryError>

Load a graph by its string UUID.

Returns None if the graph does not exist.

§Errors

Returns a MemoryError on database failure.

Source

async fn list_graphs( &self, limit: u32, ) -> Result<Vec<GraphSummary>, MemoryError>

List graphs ordered by created_at descending, limited to limit rows.

§Errors

Returns a MemoryError on database failure.

Source

async fn delete_graph(&self, id: &str) -> Result<bool, MemoryError>

Delete a graph by its string UUID.

Returns true if a row was deleted.

§Errors

Returns a MemoryError on database failure.

Dyn Compatibility§

This trait is not dyn compatible.

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