Struct TransitionDecoder 

pub struct TransitionDecoder { /* private fields */ }

Detect cognitive state transitions from topology change patterns.

Monitors a sliding window of topology metrics and compares observed deltas against registered transition patterns to detect state changes.

Implementations

impl TransitionDecoder

pub fn new(window_size: usize) -> Self

Create a new transition decoder with a given sliding window size.

The window size determines how many recent topology snapshots are retained for computing deltas.

pub fn register_pattern( &mut self, from: CognitiveState, to: CognitiveState, pattern: TransitionPattern, )

Register a transition pattern between two states.

pub fn current_state(&self) -> CognitiveState

Get the current estimated cognitive state.

pub fn set_current_state(&mut self, state: CognitiveState)

Set the current state explicitly (e.g., from an external decoder).

pub fn update(&mut self, metrics: TopologyMetrics) -> Option<StateTransition>

Push a new topology snapshot and check for state transitions.

Returns Some(StateTransition) if a transition is detected, None otherwise.

pub fn num_patterns(&self) -> usize

Number of registered transition patterns.

pub fn history_len(&self) -> usize

Number of topology snapshots in the history buffer.
