Struct TrajectoryRecorder 

pub struct TrajectoryRecorder { /* private fields */ }

Records agent trajectories for learning and pattern extraction.

Maintains a bounded FIFO buffer of TrajectoryRecords. When the buffer is full the oldest record is evicted. Callers can query by agent and extract frequency patterns from successful actions.

Implementations

impl TrajectoryRecorder

pub fn new(max_records: usize) -> Self

Create a recorder with the given capacity.

pub fn record(&mut self, record: TrajectoryRecord)

Record a trajectory point. Evicts the oldest record on overflow.

pub fn agent_trajectory(&self, agent_id: &str) -> Vec<&TrajectoryRecord>

Get all records for a specific agent.

pub fn extract_patterns(&self) -> Vec<(String, usize)>

Extract patterns: returns (action, count) pairs for successful actions, sorted by frequency descending.

pub fn len(&self) -> usize

Number of recorded trajectories.

pub fn is_empty(&self) -> bool

Whether the recorder is empty.
