Struct RestartStrategyModel 

pub struct RestartStrategyModel { /* private fields */ }

Learned restart strategy replacing fixed backoff delays and retry decisions.

Inputs (4): failure_count, failure_type_ordinal, uptime_before_failure_secs, system_load (0.0-1.0) Outputs (2): optimal_delay_ms, should_retry (>0.5 = yes)

Fallback: exponential backoff 100ms * 2^(n-1), capped at 30s; always retry.

Implementations

impl RestartStrategyModel

pub fn new() -> Self

Create a new untrained restart strategy model.

pub fn drain_events(&mut self) -> Vec<EmlEvent>

Drain accumulated EML lifecycle events for ExoChain forwarding.

pub fn is_trained(&self) -> bool

Whether the model has been trained.

pub fn training_sample_count(&self) -> usize

Number of training samples collected.

pub fn predict( &self, failure_count: u32, failure_type: u32, uptime_before_failure_secs: f64, system_load: f64, ) -> (u64, bool)

Predict restart parameters.

Returns (delay_ms, should_retry) where should_retry is true when the model’s second head exceeds 0.5.

When untrained, uses exponential backoff: 100 * 2^(failure_count-1), capped at 30_000ms, and always retries.

pub fn record( &mut self, failure_count: u32, failure_type: u32, uptime_before_failure_secs: f64, system_load: f64, actual_delay_ms: u64, recovery_succeeded: bool, )

Record a restart outcome for training.

actual_delay_ms is the delay that led to successful recovery. recovery_succeeded indicates whether the restart succeeded.

pub fn train(&mut self) -> bool

Train the model from recorded samples.
