pub struct NoOpGroupNavigator;

A no-op group navigator that returns empty results for all queries.

Trait Implementations

impl GroupNavigator for NoOpGroupNavigator

fn find_segments_in_group( &self, _: &str, _: &[&str], _: usize, ) -> Vec<OwnedSegment>

Find all segments with the given tag within a specific group instance.

fn find_segments_with_qualifier_in_group( &self, _: &str, _: usize, _: &str, _: &[&str], _: usize, ) -> Vec<OwnedSegment>

Find segments matching a tag + qualifier within a group instance.

fn group_instance_count(&self, _: &[&str]) -> usize

Count repetitions of a group at the given path.

fn find_segments_in_instance( &self, segment_id: &str, path: &[(&str, usize)], ) -> Vec<OwnedSegment>

Find all segments with the given tag in one group instance, addressed by the repetition index at every level: [("SG4", 1), ("SG8", 0)] is the first SG8 of the second SG4.

fn find_segments_in_subtree( &self, segment_id: &str, path: &[(&str, usize)], ) -> Vec<OwnedSegment>

Like find_segments_in_instance, but including the segments of every group nested in that instance: “in dieser SG8 … SG10 CCI” reads the SG8’s SG10s too.

fn has_any_segment_in_group( &self, _group_path: &[&str], _instance_index: usize, ) -> bool

Check if a group instance has any segments at all.

fn instance_has_mig_number( &self, _group_path: &[&str], _instance_index: usize, _mig_number: &str, ) -> bool

Check if a group instance belongs to the MIG variant identified by mig_number.

fn child_group_instance_count( &self, parent_path: &[&str], parent_instance: usize, child_group_id: &str, ) -> usize

Count repetitions of a child group within a specific parent group instance.

fn find_segments_in_child_group( &self, segment_id: &str, parent_path: &[&str], parent_instance: usize, child_group_id: &str, child_instance: usize, ) -> Vec<OwnedSegment>

Find all segments with the given tag within a child group instance.

fn extract_value_in_group( &self, segment_id: &str, element_index: usize, component_index: usize, group_path: &[&str], instance_index: usize, ) -> Option<String>

Extract a single value from the first matching segment in a group instance.
