Implementations

impl SessionGraph

pub fn append_active_read_delta(&mut self, messages: &[Message])

pub fn append_active_read_delta_for_agent_frame( &mut self, agent_frame_id: &str, messages: &[Message], )

pub fn from_nodes( nodes: Vec<SessionNodeRecord>, leaf_node_id: Option<String>, ) -> Self

pub fn append_message(&mut self, message: Message) -> String

pub fn append_plugin( &mut self, plugin_type: impl Into<String>, body: Value, ) -> String

pub fn active_path_nodes(&self) -> Vec<&SessionNodeRecord>

pub fn append_protocol_event(&mut self, event: ProtocolEvent) -> String

pub fn user_message_count(&self) -> usize

pub fn first_user_message(&self) -> String

pub fn branch_to(&mut self, node_id: Option<String>)

pub fn set_leaf_node_id(&mut self, node_id: Option<String>)

pub fn push_node_record(&mut self, node: SessionNodeRecord)

pub fn extend_node_records<I>(&mut self, nodes: I)

where I: IntoIterator<Item = SessionNodeRecord>,

pub fn extend_active_path(&mut self, nodes: Vec<SessionNodeRecord>)

Append nodes that extend the current active path, advancing the leaf to the last node and updating the cache incrementally instead of invalidating it. Use this when the appended nodes are genuinely new descendants of the current leaf — e.g. the turn-driver merging turn-local graph editor deltas into the base graph. Use extend_node_records + set_leaf_node_id for store-side replay paths that don’t follow the active-path append shape.

pub fn active_path_contains(&self, node_id: &str) -> bool

pub fn heal_orphaned_leaf(&mut self) -> bool

If leaf_node_id points to a node that no longer exists in self.nodes (e.g. after compaction rewrote the graph, or a stored session referenced a node that was later purged), fall back to the most recent message node. Returns true if the leaf was repaired. Call this on load paths where an orphan leaf would project to an empty transcript and silently drop the user’s history.

pub fn fork_current_path(&self) -> SessionGraph

pub fn find_node(&self, node_id: &str) -> Option<&SessionNodeRecord>

pub fn node_index(&self, node_id: &str) -> Option<usize>

pub fn replace_active_read_state(&mut self, messages: &[Message])

pub fn replace_active_read_state_for_agent_frame( &mut self, agent_frame_id: &str, messages: &[Message], )

pub fn from_active_read_state(messages: &[Message]) -> Self

pub fn message_tree(&self) -> Vec<SessionMessageTreeNode>
