Execution order about animation rigging and constraints

hello,

https://docs.unity3d.com/2019.4/Documentation/Manual/Constraints.html
https://docs.unity3d.com/Packages/com.unity.animation.rigging@0.2/manual/index.html

Is execution order of Constraints and AnimationRigging guaranteed?
If so, which is faster?

https://docs.unity3d.com/Manual/ExecutionOrder.html
Unity manual does not show this.

Constraints are preformed just before LateUpdate.(They are performed in an internal function called PreLateUpdate.)
I get to know this from https://issuetracker.unity3d.com/issues/sampling-the-position-of-the-gameobject-with-update-function-does-not-yield-the-correct-position
which is mentioned in https://discussions.unity.com/t/774714

I don't konw about AnimationRigging.
