Expand description

A trait to allow responding to a traversal designed to observe all entries in a tree, recursively while keeping track of paths if desired.

Required methods

Sets the full path path in front of the queue so future calls to push and pop components affect it instead.

Append a component to the end of a path, which may be empty.

Append a component to the end of a path, which may be empty.

Removes the last component from the path, which may leave it empty.

Observe a tree entry that is a tree and return an instruction whether to continue or not. Action::Skip can be used to prevent traversing it, for example if it’s known to the caller already.

The implementation may use the current path to learn where in the tree the change is located.

Observe a tree entry that is NO tree and return an instruction whether to continue or not. Action::Skip has no effect here.

The implementation may use the current path to learn where in the tree the change is located.
