Struct lyon_tessellation::geometry_builder::NoOutput

pub struct NoOutput { /* fields omitted */ }

A geometry builder that does not output any geometry.

Mostly useful for testing.

Methods

impl NoOutput

fn new() -> Self

Trait Implementations

impl<T> GeometryBuilder<T> for NoOutput

fn begin_geometry(&mut self)

Called at the beginning of a generation.

fn add_vertex(&mut self, _: T) -> VertexId

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

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 occured while producing the geometry and we won't be able to finish.

impl<V, I> GeometryReceiver<V, I> for NoOutput

fn set_geometry(&mut self, _vertices: &[V], _indices: &[I])
