Struct ArcGenerator 

pub struct ArcGenerator { /* private fields */ }

Generates SVG path d strings for arc segments (pie/doughnut slices).

Implementations

impl ArcGenerator

pub fn new(inner_radius: f64, outer_radius: f64) -> Self

Create a new ArcGenerator. Use inner_radius=0 for pie charts, >0 for doughnut charts.

pub fn corner_radius(self, r: f64) -> Self

Set the corner radius for rounded corners (not yet implemented, stored for future use).

pub fn generate(&self, start_angle: f64, end_angle: f64) -> String

Generate an SVG path for an arc from start_angle to end_angle.

Angles are in radians, 0 = 12 o’clock, clockwise. The arc is centered at the origin.
