Struct PolygonZoneMonitor 

pub struct PolygonZoneMonitor<'a, const N: usize> { /* private fields */ }

Tracks polygon membership transitions for at most N tracks.

Implementations

impl<'a, const N: usize> PolygonZoneMonitor<'a, N>

pub const fn new(zone_id: ZoneId, polygon: Polygon<'a>) -> Self

Creates a monitor for polygon using caller-selected fixed track capacity.

pub fn update( &mut self, track_id: TrackId, point: Point, output: &mut [VisionEvent], ) -> Result<usize, CoreError>

Records a point sample and writes its membership event to output[0] when needed.

Errors

Returns CoreError::InsufficientCapacity when no track slot or required event-output slot is available. On error, the monitor state is unchanged.

pub fn forget_track(&mut self, track_id: TrackId) -> bool

Removes a track’s stored membership state without emitting an event.
