pub struct DiskTree { /* private fields */ }

Arena-allocated directory tree

Implementations

impl DiskTree

pub fn new(root_path: PathBuf) -> Self

pub fn add_node( &mut self, name: String, kind: NodeKind, path: PathBuf, parent: NodeId, ) -> NodeId

Add a new node and return its ID

pub fn get(&self, id: NodeId) -> Option<&TreeNode>

Get a reference to a node

pub fn get_mut(&mut self, id: NodeId) -> Option<&mut TreeNode>

Get a mutable reference to a node

pub fn root(&self) -> &TreeNode

Get the root node

pub fn root_path(&self) -> &Path

Get the root path

pub fn rebuild_paths(&mut self)

Reconstruct paths and UI state for all nodes after deserialization Must be called after loading from cache since paths and is_expanded are not serialized

pub fn len(&self) -> usize

Get total number of nodes (including tombstones)

pub fn live_count(&self) -> usize

Get count of live (non-tombstone) nodes

pub fn is_empty(&self) -> bool

Check if tree is empty (only has root)

pub fn set_size(&mut self, id: NodeId, size: u64)

Set size for a node

pub fn aggregate_sizes(&mut self)

Propagate sizes from children to parents (bottom-up)

pub fn sort_by_size(&mut self)

Sort all children by size descending

pub fn toggle_expanded(&mut self, id: NodeId)

Toggle expanded state for a node

pub fn set_expanded(&mut self, id: NodeId, expanded: bool)

Set expanded state for a node

pub fn visible_nodes(&self, root: NodeId) -> Vec<NodeId>

Get visible nodes in tree order (respecting expansion state)

pub fn path_to_node(&self, id: NodeId) -> Vec<NodeId>

Get the path from root to a node

pub fn breadcrumbs(&self, id: NodeId) -> String

Get breadcrumb string for a node

pub fn expand_to(&mut self, id: NodeId)

Expand all ancestors of a node

pub fn total_size(&self) -> u64

Get total size of the tree

pub fn total_files(&self) -> u64

Get total file count

pub fn iter(&self) -> impl Iterator<Item = &TreeNode>

Iterator over all live nodes (skips tombstones)

pub fn find_by_path(&self, path: &Path) -> Option<NodeId>

Find a node by its path

pub fn remove_node(&mut self, id: NodeId) -> u64

Remove node and descendants, return bytes freed Does NOT perform filesystem operations - only updates tree structure
