Type Aliases

• Blip
  Single datapoint generated by a client detecting an emitter: coordinates of the phone (if any), macaddr, ssid
• Blips
• BloomHash
• GeoSegment
• Lsm 🔒
  Location accuracy as standard deviation expressed in meters
• Mac
• MiniMap
  Used during lookup to overlay one minimap from each emitter. The u8 counts the number of matches (and u8 is big enough)
• Plocations 🔒
