Fields

model: Model<Vertex>

stale_flag: bool

Used to garbage-collect tethers that no longer exist.

Because a tether is not an entity, but instead a relationship between two entities, there is no single ‘event’ that we can listen to in order to determine that a tether has been broken. Instead, every tick, we go through the set of tethers that we observe in the world and mark their entries in the tethers map below with a flag. At the end of the tick, every unmarked tether in the tethers map below can be deleted.

Every tick, the ‘alive’ state of the flag flips between true and false to avoid the need to wastefully reset the flag of every alive tether on each tick (this is a common optimisation in some garbage collection algorithms too).

tethers: HashMap<(Uid, Uid), (BoundLocals, bool)>
