Struct LarkBitableCheckpointer 

pub struct LarkBitableCheckpointer { /* private fields */ }

Bitable-backed graph checkpoint store.

Persists [synaptic_graph::checkpoint::Checkpoint] snapshots into a Feishu Bitable table, enabling human-in-the-loop workflows via the Feishu UI.

The Bitable table must contain the following fields:

• thread_id (Text)
• checkpoint_id (Text)
• parent_id (Text)
• state (Text — JSON)
• next_node (Text)
• metadata (Text — JSON)
• created_at (Text — Unix timestamp string)

This struct is always compiled. The [synaptic_graph::checkpoint::Checkpointer] impl is gated behind #[cfg(feature = "checkpointer")].

Implementations

impl LarkBitableCheckpointer

pub fn new( config: LarkConfig, app_token: impl Into<String>, table_id: impl Into<String>, ) -> Self

Create a new checkpointer.

• config — Lark application credentials and base URL.
• app_token — Bitable app token (e.g. "bascnXxx").
• table_id — Table ID inside that Bitable (e.g. "tblXxx").

pub fn app_token(&self) -> &str

Return the Bitable app token this checkpointer targets.
