Implementations

impl Tree

pub fn new(root: PathBuf, hidden: bool) -> Self

pub fn display_root(&self) -> Cow<'_, str>

root, or — on the synthetic drives level — a label for it, since an empty path would otherwise render as a blank title bar.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn get(&self, i: usize) -> Option<&Entry>

pub fn reload(&mut self)

pub fn toggle(&mut self, i: usize)

Expand or collapse the directory at i. No-op on files.

pub fn parent_of(&self, i: usize) -> Option<usize>

Index of the entry that i is nested under.

pub fn up(&mut self) -> bool

Re-root one directory up. At a drive root on Windows, steps out to the synthetic drives level ([load]) instead of stopping, since C:\ has no parent the way nested directories do. False once there is truly nothing above (the drives level itself, or / on other platforms).
