Struct StateLine 

pub struct StateLine {
    pub domain: StateDomain,
    pub activity: f32,
    pub trend: Trend,
    pub hotspots: Vec<GeoHotspot>,
    pub last_updated: WorldTick,
    pub activity_history: Vec<f32>,
}

A single domain’s state line — tracks activity level and trend.

Fields

domain: StateDomain

The domain this state line tracks.

activity: f32

Normalised activity level (0.0–1.0).

trend: Trend

Current trend direction.

hotspots: Vec<GeoHotspot>

Spatial hotspots within this domain.

last_updated: WorldTick

Tick of last update.

activity_history: Vec<f32>

Recent activity history for trend detection (not serialised).

Implementations

impl StateLine

pub fn new(domain: StateDomain) -> Self

Create a new state line at zero activity.

pub fn update_activity(&mut self, sample: f32, tick: WorldTick)

Apply an exponential moving average (EMA) update with alpha = 0.3, then detect the current trend.
