Struct Callout 

pub struct Callout { /* private fields */ }

A text label and leader, with explicitly authored label dimensions.

Implementations

impl Callout

pub fn new(text: impl Into<String>, target: Point, bounds: Rect) -> Self

Captures a target and opposite-corner label bounds; validation is deferred.

pub fn color(self, color: Color) -> Self

Replaces the text and leader color.

pub fn font_size(self, size: f64) -> Self

Replaces logical font size, valid in (0,4096].

pub fn leader_width(self, width: f64) -> Self

Replaces the positive logical leader width.

pub fn node(self) -> Result<Node>

Builds ordinary text and path nodes without discovering fonts.

pub fn node_in(self, context: &SceneContext<'_>, camera: Camera) -> Result<Node>

Projects the world target while keeping label dimensions in viewport space. Outside targets hide the whole callout, but invalid hidden settings still fail.

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

Performs copy-assignment from source.
