Struct Predictive 

pub struct Predictive { /* private fields */ }

Markov-chain-driven tick strategy.

Learns screen transition patterns and allocates tick budget proportionally to transition probability. High-probability next screens tick at near-full rate; low-probability screens are aggressively throttled.

See module-level docs for architecture details.

Implementations

impl Predictive

pub fn new(config: PredictiveStrategyConfig) -> Self

Create a new predictive strategy with the given config.

pub fn with_counter( config: PredictiveStrategyConfig, counter: TransitionCounter<String>, ) -> Self

Create with pre-loaded transition data (e.g., from persistence).

pub fn predictor(&self) -> &MarkovPredictor<String>

Access the underlying predictor.

pub fn counter(&self) -> &TransitionCounter<String>

Access the underlying transition counter.

pub fn is_dirty(&self) -> bool

Whether there is unsaved transition data.
