Struct Tree 

pub struct Tree { /* private fields */ }

A node in a hierarchy. Mirrors rich.tree.Tree.

Implementations

impl Tree

pub fn new(label: impl Into<Cell>) -> Self

A new tree/subtree with the given label. A string label is console markup, as upstream’s Tree("[b]root") is; pass a Text for a literal one.

pub fn highlight(self, highlight: bool) -> Self

Highlight string labels (upstream Tree(highlight=…), default off). Upstream renders every label with the root’s setting.

pub fn add(&mut self, label: impl Into<Cell>) -> &mut Tree

Add a child with label, returning a mutable reference to it so further descendants can be attached. Mirrors Tree.add.

Trait Implementations

impl Drop for Tree

fn drop(&mut self)

Drop descendants from an explicit stack: the derived drop recurses once per level and overflows the stack on a very deep tree.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Renderable for Tree

fn measure(&self, console: &Console, options: &ConsoleOptions) -> Measurement

Port of Tree.__rich_measure__: the widest label plus its indent of four cells per level, for both bounds.

fn rich_render( &self, console: &Console, options: &ConsoleOptions, ) -> Vec<Segment>

fn fit_to_measurement(&self) -> bool

Whether a top-level Console::print shrinks this renderable to its measured width. Upstream renders every top-level renderable at the full console width, so the default is false; an extension may opt in.
