Struct GroupNavigator 

pub struct GroupNavigator {
    pub root: ShdfGroup,
}

Navigate an ShdfGroup hierarchy using HDF5-style slash-separated paths.

Example

let mut root = ShdfGroup::new("root");
let mut sim  = ShdfGroup::new("simulation");
sim.add_dataset_f64("time", vec![3], vec![0.0, 0.5, 1.0]);
root.add_child(sim);
let nav = GroupNavigator::new(root);
assert!(nav.get_dataset("/simulation/time").is_some());

Fields

root: ShdfGroup

Root group of the hierarchy.

Implementations

impl GroupNavigator

pub fn new(root: ShdfGroup) -> Self

Create a navigator wrapping a root group.

pub fn get_dataset(&self, path: &str) -> Option<&Dataset>

Resolve a slash-separated path such as "/root/simulation/atoms/positions" and return the terminal dataset if it exists.

The first path component must match the root group name.

pub fn all_paths(&self) -> Vec<String>

Return all dataset paths reachable from the root, in DFS order.

pub fn total_datasets(&self) -> usize

Count total datasets reachable from the root.
