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§

source

fn pop_front_tracked_path_and_set_current(&mut self)

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

source

fn push_back_tracked_path_component(&mut self, component: &BStr)

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

source

fn push_path_component(&mut self, component: &BStr)

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

source

fn pop_path_component(&mut self)

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

source

fn visit_tree(&mut self, entry: &EntryRef<'_>) -> Action

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.

source

fn visit_nontree(&mut self, entry: &EntryRef<'_>) -> Action

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.
