Implementations

impl ModelVersionManager

pub fn new() -> Self

Create a new version manager.

pub fn with_thresholds(thresholds: QualityThresholds) -> Self

pub fn with_max_history(self, max: usize) -> Self

Set maximum history size.

pub fn active_version(&self) -> Option<&ModelEntry>

Get current active version.

pub fn versions(&self) -> impl Iterator<Item = &ModelEntry>

Get all versions.

pub fn version_count(&self) -> usize

Get version count.

pub fn thresholds(&self) -> &QualityThresholds

Get quality thresholds.

pub fn register_version(&mut self, entry: ModelEntry) -> Result<bool, String>

Register a new model version.

Returns Ok(true) if version was activated, Ok(false) if registered but not activated (due to quality issues), or Err if registration failed.

pub fn rollback( &mut self, reason: impl Into<String>, ) -> Result<RollbackResult, String>

pub fn rollback_history(&self) -> &[RollbackResult]

Get rollback history.

pub fn check_quality( &self, current_metrics: &ModelQualityMetrics, ) -> Option<String>

Check if current model needs rollback based on new metrics.

Implements Jidoka (stop the line) principle.

pub fn auto_rollback_if_needed( &mut self, current_metrics: &ModelQualityMetrics, ) -> Option<RollbackResult>

Auto-rollback if quality check fails.

pub fn to_markdown(&self) -> String
