Struct lyon_tessellation::geometry_builder::NoOutput
source · pub struct NoOutput { /* private fields */ }
Expand description
A geometry builder that does not output any geometry.
Mostly useful for testing.
Implementations
Trait Implementations
sourceimpl FillGeometryBuilder for NoOutput
impl FillGeometryBuilder for NoOutput
sourcefn add_fill_vertex(
&mut self,
_vertex: FillVertex<'_>
) -> Result<VertexId, GeometryBuilderError>
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. Read more

impl GeometryBuilder for NoOutput
sourcefn add_triangle(&mut self, a: VertexId, b: VertexId, c: VertexId)
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. Read more
sourcefn begin_geometry(&mut self)
fn begin_geometry(&mut self)
Called at the beginning of a generation. Read more
sourcefn end_geometry(&mut self)
fn end_geometry(&mut self)
Called at the end of a generation.
Returns the number of vertices and indices added since the last time begin_geometry was
called. Read more
sourcefn abort_geometry(&mut self)
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. Read more

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. Read more
