Struct TreeNode 

pub struct TreeNode {
    pub path: PathBuf,
    pub is_dir: bool,
    pub is_expanded: bool,
    pub is_loaded: bool,
    pub is_selected: bool,
    pub children: Vec<TreeNode>,
    pub error: Option<ScanIssue>,
}

One directory entry in the tree.

Fields

path: PathBuf

Absolute path.

is_dir: bool

true for directories.

is_expanded: bool

true if the node’s children are drawn on screen.

is_loaded: bool

true once a scan has populated (or errored) this node.

is_selected: bool

Derived view hint: true iff this path is in the tree’s crate::DirectoryTree::selected_paths set.

Re-synced after every selection mutation; never authoritative — paths remain selected while their node is unloaded, filtered out, or temporarily absent.

children: Vec<TreeNode>

Filtered children; empty until loaded.

error: Option<ScanIssue>

Set when the scan for this directory failed.

Implementations

impl TreeNode

pub fn file_name(&self) -> &OsStr

Final path component, for use as a row label.

pub fn find(&self, path: &Path) -> Option<&TreeNode>

Find the node for path in this subtree.

Descends only into the child whose path is a component-wise prefix of path, so lookup cost is proportional to depth, not to tree size.

Trait Implementations

impl Clone for TreeNode

fn clone(&self) -> TreeNode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TreeNode

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for TreeNode

fn eq(&self, other: &TreeNode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
