Struct LineZoneMonitor 

pub struct LineZoneMonitor<const N: usize> { /* private fields */ }

Tracks crossings of a finite directed line segment for at most N tracks.

Implementations

impl<const N: usize> LineZoneMonitor<N>

pub const fn new(zone_id: ZoneId, segment: LineSegment) -> Self

Creates a monitor for segment 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 crossing 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 crossing state without emitting an event.
