Struct FileTree 

pub struct FileTree { /* private fields */ }

In-memory file tree tracking directory structure during formatting.

Implementations

impl FileTree

pub fn new(root_inode: InodeNumber, name: &str) -> Self

Create a new file tree with a single root node.

pub fn root(&self) -> usize

Return the index of the root node.

pub fn node(&self, idx: usize) -> &FileTreeNode

Borrow a node by index.

pub fn node_mut(&mut self, idx: usize) -> &mut FileTreeNode

Mutably borrow a node by index.

pub fn lookup(&self, path: &Path) -> Option<usize>

Look up a node by path, walking the tree from the root.

The path is split into components. A leading “/” or empty first component is skipped so that both “/foo/bar” and “foo/bar” resolve identically. Returns None if any component is not found.

pub fn add_child(&mut self, parent: usize, node: FileTreeNode) -> usize

Add a child node under parent, returning the new node’s index.

pub fn remove_child(&mut self, parent: usize, name: &str)

Remove the first child with the given name from parent’s children list.

The node itself remains in the vector (indices are stable), but the parent no longer references it.

pub fn node_path(&self, idx: usize) -> PathBuf

Reconstruct the full path of a node by walking the parent chain.
