atomic-core/src/output/repo/tree.rs:938–947

Build a tree structure from flat paths. Organizes items into a hierarchical structure by parent-child relationships. # Arguments `items` - Flat list of tree items # Returns A map from parent path to child items. # Example ```rust use atomic_core::output::repo::{build_tree_hierarchy, TreeItem}; use atomic_core::types::{Inode, Position}; let items = vec![ TreeItem::file("src/main.rs", Inode:

(items: &[TreeItem])

/// assert!(hierarchy.get("src").is_some());
/// ```
pub fn build_tree_hierarchy(items: &[TreeItem]) -> HashMap<String, Vec<&TreeItem>> {
    let mut hierarchy: HashMap<String, Vec<&TreeItem>> = HashMap::new();

    for item in items {
        let parent = item.parent_path().to_string();
        hierarchy.entry(parent).or_default().push(item);
    }

    hierarchy
}
