Render stream abstraction.

Associated Types

type CommandBuffer: CommandBuffer<R>

Command buffer type to constraint the Renderer.

type Output: Output<R>

Constrained Output type.

Required Methods

fn get_output(&self) -> &Self::Output

Get the output only.

fn access(&mut self) -> (&mut Renderer<R, Self::CommandBuffer>, &Self::Output)

Access both of the stream components.

Provided Methods

fn get_aspect_ratio(&self) -> f32

Get width/height aspect, needed for projections.

fn clear(&mut self, data: ClearData)

Clear the canvas.

fn blit_on<I: Output<R>>(&mut self, source: &I, source_rect: Rect, dest_rect: Rect, mirror: Mirror, mask: Mask)

Blit on this stream from another Output.

fn blit_to<O: Output<R>>(&mut self, destination: &O, dest_rect: Rect, source_rect: Rect, mirror: Mirror, mask: Mask)

Blit this stream to another Output.

fn draw<B: Batch<R>>(&mut self, batch: &B) -> Result<(), DrawError<B>>

Draw a simple Batch.

fn draw_instanced<B: Batch<R>>(&mut self, batch: &B, count: InstanceCount, base: VertexCount) -> Result<(), DrawError<B>>

Draw an instanced Batch.

fn flush<D>(&mut self, device: &mut D) where D: Device<Resources=R, CommandBuffer=Self::CommandBuffer>

Execute everything and clear the command buffer.
