TrackingPolicy

Struct TrackingPolicy 

Source
pub struct TrackingPolicy { /* private fields */ }
Expand description

Track acquisition and loss thresholds: vessel settings.

Validated by TrackingPolicy::new: at least one fix to acquire, lost timeout ≥ stale timeout, positive maximum speed.

Implementations§

Source§

impl TrackingPolicy

Source

pub fn new( fixes_to_acquire: u8, stale_after: Duration, lost_after: Duration, max_speed: Speed, ) -> Result<Self>

Policy from four thresholds; full picture refuses newcomers.

  • fixes_to_acquire: observations before TrafficEvent::TargetAcquired (3 is the radar convention; AIS can be trusted from the first).
  • stale_after: time since the last observation after which the track is marked stale in the view (still shown and extrapolated).
  • lost_after (≥ stale_after): time after which Traffic::sweep drops the track with TrafficEvent::TargetLost.
  • max_speed: maximum plausible target speed; an observation implying more is rejected as an implausible jump (swapped track, corrupt report).
§Errors

KernelError::OutOfRange for zero fixes, lost_after < stale_after, or a non-positive speed.

Source

pub const fn when_full(self, when_full: WhenFull) -> Self

Sets the full-picture behaviour.
