Hashes the essential components of this value by feeding them into the
given hasher.
Implement this method to conform to theHashableprotocol. The
components used for hashing must be the same as the components compared
in your type’s==operator implementation. Callhasher.combine(_:)with each of these components.
Important
In your implementation ofhash(into:),
don’t callfinalize()on thehasherinstance provided,
or replace it with a different instance.
Doing so may become a compile-time error in the future.
Hash values are not guaranteed to be equal across different executions of
your program. Do not save hash values to use during a future execution.
Important
hashValueis deprecated as aHashablerequirement. To
conform toHashable, implement thehash(into:)requirement instead.
The compiler provides an implementation forhashValuefor you.
Specifies whether this marker should preserve its size or not regardless
of distance from camera. By default the marker is scaled based on
distance from camera/tilt.
The zIndex compared to other 3D markers. By default,Markersare
displayed according to their vertical position on screen, with lowerMarkersappearing in front ofMarkerfarther up the screen. Note
thatzIndexis also used to help determine relative priority betweenCollisionBehavior.optionalAndHidesLowerPriority3D markers. A higherzIndex` value indicates higher priority.
