Struct StrokeLineResult 

pub struct StrokeLineResult {
    pub positions: Vec<[f64; 2]>,
    pub indices: Vec<u32>,
    pub normals: Vec<[f64; 2]>,
    pub distances: Vec<f64>,
    pub cap_join: Vec<f32>,
}

Output of stroke_line_styled.

Fields

positions: Vec<[f64; 2]>

Vertex positions [lon, lat] in degree space.

indices: Vec<u32>

Triangle indices into positions.

normals: Vec<[f64; 2]>

Per-vertex extrusion normal [nx, ny] (unit-length, perpendicular to centreline). Same length as positions.

distances: Vec<f64>

Per-vertex cumulative distance along the polyline centreline (degrees). Same length as positions.

cap_join: Vec<f32>

Per-vertex cap/join flag. 1.0 for vertices belonging to round cap or round join fan geometry (center and perimeter), 0.0 for ribbon body, bevel, miter, and square cap vertices.

The GPU shader uses this flag to switch from linear edge AA (ribbon body) to SDF circle-based AA (round caps/joins).
