Struct InMemoryCheckpointer 

pub struct InMemoryCheckpointer { /* private fields */ }

In-memory checkpointer for testing and short-lived graphs.

Data lives only as long as the process. For durable persistence, use the SurrealDB checkpointer from pe-memory.

Implementations

impl InMemoryCheckpointer

pub fn new() -> Self

Create a new empty in-memory checkpointer.
