Trait Implementations

impl RenderTarget for AlphaRenderTarget

fn new( texture_id: CacheTextureId, _: DeviceIntSize, gpu_supports_fast_clears: bool, _: DeviceIntRect, ) -> Self

Creates a new RenderTarget of the given type.

fn texture_id(&self) -> CacheTextureId

fn add_task( &mut self, task_id: RenderTaskId, ctx: &RenderTargetContext<'_, '_>, gpu_cache: &mut GpuCache, gpu_buffer_builder: &mut GpuBufferBuilder, render_tasks: &RenderTaskGraph, clip_store: &ClipStore, transforms: &mut TransformPalette, )

Associates a RenderTask with this target. That task must be assigned to a region returned by invoking allocate() on this target.

fn needs_depth(&self) -> bool

fn build( &mut self, _ctx: &mut RenderTargetContext<'_, '_>, _gpu_cache: &mut GpuCache, _render_tasks: &RenderTaskGraph, _prim_headers: &mut PrimitiveHeaders, _transforms: &mut TransformPalette, _z_generator: &mut ZBufferIdGenerator, _prim_instances: &[PrimitiveInstance], _cmd_buffers: &CommandBufferList, _gpu_buffer_builder: &mut GpuBufferBuilder, )

Optional hook to provide additional processing for the target at the end of the build phase.

impl Serialize for AlphaRenderTarget

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
