Enum RiskOverlayTrigger 

pub enum RiskOverlayTrigger {
    Friction(FrictionLevel),
    Proximity,
}

Why the ActiveOverlay::Risk overlay opened.

Populated at open-time by the auto-open hook so the widget can render context-specific copy (L3 “approaching guardrail”, L4 “engine halted”), and so the rate-limiter can distinguish “same trigger, operator already saw it” from “new escalation, operator must see it again within the cooldown”.

Variants

Friction(FrictionLevel)

The operator-state snapshot the engine returned carries FrictionLevel::L3 (TILT + guardrail proximity) or L4 (TILT + halt). The level is carried so re-open logic can detect L3 → L4 escalations and bypass the dismiss-cooldown.

Proximity

The engine’s Risk.drawdown_pct is within AppState::GUARDRAIL_PROXIMITY_PP of its Risk.last_drawdown_alert_pct threshold. This fires even without an L3 classifier verdict — the engine’s own proximity reading is authoritative for “you are about to trip a guardrail.”

Trait Implementations

impl Clone for RiskOverlayTrigger

fn clone(&self) -> RiskOverlayTrigger

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RiskOverlayTrigger

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for RiskOverlayTrigger

fn eq(&self, other: &RiskOverlayTrigger) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
