Struct lyon_tessellation::geometry_builder::NoOutput

pub struct NoOutput { /* fields omitted */ }

A geometry builder that does not output any geometry.

Mostly useful for testing.

Implementations

impl NoOutput

pub fn new() -> Self

Trait Implementations

impl FillGeometryBuilder for NoOutput

fn add_fill_vertex(
    &mut self,
    _vertex: FillVertex<'_>
) -> Result<VertexId, GeometryBuilderError>

Inserts a vertex, providing its position, and optionally a normal. Returns a vertex id that is only valid between begin_geometry and end_geometry.

impl GeometryBuilder for NoOutput

fn begin_geometry(&mut self)

Called at the beginning of a generation.

fn add_triangle(&mut self, a: VertexId, b: VertexId, c: VertexId)

Insert a triangle made of vertices that were added after the last call to begin_geometry.

fn end_geometry(&mut self) -> Count

Called at the end of a generation. Returns the number of vertices and indices added since the last time begin_geometry was called.

fn abort_geometry(&mut self)

abort_geometry is called instead of end_geometry if an error occurred while producing the geometry and we won't be able to finish.

impl StrokeGeometryBuilder for NoOutput

fn add_stroke_vertex(
    &mut self,
    _: StrokeVertex<'_, '_>
) -> Result<VertexId, GeometryBuilderError>

Inserts a vertex, providing its position, and optionally a normal. Returns a vertex id that is only valid between begin_geometry and end_geometry.
