Struct SessionIndex 

pub struct SessionIndex { /* private fields */ }

Maps each session_id to a sorted list of node IDs in that session.

Implementations

impl SessionIndex

pub fn new() -> Self

Create a new, empty session index.

pub fn get_session(&self, session_id: u32) -> &[u64]

Get all node IDs from a specific session.

pub fn get_sessions(&self, session_ids: &[u32]) -> Vec<u64>

Get all node IDs from multiple sessions, merged and sorted.

pub fn session_ids(&self) -> Vec<u32>

Get all known session IDs.

pub fn session_count(&self) -> usize

Count sessions.

pub fn node_count(&self, session_id: u32) -> usize

Count nodes in a session.

pub fn rebuild(&mut self, nodes: &[CognitiveEvent])

Rebuild the entire index from a slice of nodes.

pub fn add_node(&mut self, event: &CognitiveEvent)

Incrementally add a new node.

pub fn remove_node(&mut self, id: u64, session_id: u32)

Remove a node from the index.

pub fn clear(&mut self)

Clear the index.

pub fn len(&self) -> usize

Number of total entries across all sessions.

pub fn is_empty(&self) -> bool

Whether the index is empty.

pub fn inner(&self) -> &HashMap<u32, Vec<u64>>

Get a reference to the underlying map (for serialization).

impl Default for SessionIndex

fn default() -> Self
