A trait to allow responding to a traversal designed to figure out the changes to turn tree A into tree B.

Associated Types

type PathId: Clone + Default[src]

A type capable of uniquely identifying paths in a tree.

Required methods

fn set_current_path(&mut self, id: Self::PathId)[src]

Sets the path associated with the given id so future calls to push and pop components affect it instead.

fn push_tracked_path_component(&mut self, component: &BStr) -> Self::PathId[src]

Append a component to the end of a path, which may be empty, and associate it with the returned path id.

fn push_path_component(&mut self, component: &BStr)[src]

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

fn pop_path_component(&mut self)[src]

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

fn visit(&mut self, change: Change) -> Action[src]

Record a change and return an instruction whether to continue or not.

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