Fields

phase: RolloutPhase

last_transition_ms: i64

transition_count: u32

rolled_back_from: Option<RolloutPhase>

trigger: RollbackTrigger

recent_decisions: VecDeque<RolloutDecisionSample>

Rolling window of recent decision outcomes for rollback evaluation.

Implementations

impl RolloutTracker

pub fn new(phase: RolloutPhase) -> Self

Create a tracker starting in the given phase.

pub fn advance(&mut self) -> bool

Advance to the next phase. Returns true if the phase changed.

pub fn rollback(&mut self)

Roll back to Shadow phase, recording what phase we rolled back from.

pub fn set_phase(&mut self, phase: RolloutPhase)

Set an explicit phase (for operator override).

pub fn record_decision( &mut self, latency_ms: u64, was_error: bool, was_false_positive: bool, ) -> bool

Record a decision sample and check rollback triggers. Returns true if a rollback was triggered.

pub fn window_stats(&self) -> RollbackWindowStats

Compute window statistics for the current evaluation window.

Trait Implementations

impl Clone for RolloutTracker

fn clone(&self) -> RolloutTracker

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
