pub fn clear()Expand description
Forget everything the receiver said.
Called when the receiver is switched off: a position from before is a position the device may no longer be at, and reporting it because it was the last one seen is how a tracker ends up insisting it is somewhere it left hours ago.
The advertised position is not the receiver’s to forget: it is a claim the operator made, or one they froze by switching auto-update off, and it lives on the session either way.
