Struct TreeNode 

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

A single node in the directory tree.

All fields are public so downstream code (tests, custom renderers built on top of the widget’s state) can inspect them, but the widget itself drives mutation through DirectoryTree::update.

Fields

path: PathBuf

Full path of the entry.

is_dir: bool

true if the entry is a directory.

is_expanded: bool

true if the directory is currently expanded in the UI. Always false for files.

is_loaded: bool

true if this directory has already been scanned at least once, even if the scan returned zero children. Distinguishes “scanned and empty” from “not scanned yet” in the view.

children: Vec<TreeNode>

Direct children. Empty until is_loaded is true.

is_selected: bool

true if the user has this node selected.

error: Option<Error>

Populated when a scan of this directory failed. For files this is always None. The view layer uses this to render a greyed-out or error-tinted row.
