Struct GlyphonTextRender 

pub struct GlyphonTextRender { /* private fields */ }

A text renderer Pipeline for rendering text using the Glyphon engine.

This struct manages font atlas, cache, viewport, and swash cache for efficient text rendering.

Example

use tessera_ui_basic_components::pipelines::text::GlyphonTextRender;

let pipeline = GlyphonTextRender::new(&device, &queue, &config, sample_count);

Implementations

impl GlyphonTextRender

pub fn new( gpu: &Device, queue: &Queue, config: &SurfaceConfiguration, sample_count: u32, ) -> Self

Creates a new text renderer pipeline.

Parameters

• gpu: The wgpu device.
• queue: The wgpu queue.
• config: Surface configuration.
• sample_count: Multisample count for anti-aliasing.

Trait Implementations

impl DrawablePipeline<TextCommand> for GlyphonTextRender

fn draw( &mut self, gpu: &Device, gpu_queue: &Queue, config: &SurfaceConfiguration, render_pass: &mut RenderPass<'_>, commands: &[(&TextCommand, PxSize, PxPosition)], _scene_texture_view: &TextureView, _clip_rect: Option<PxRect>, )

Renders a batch of draw commands.

fn begin_frame( &mut self, gpu: &Device, gpu_queue: &Queue, config: &SurfaceConfiguration<Vec<TextureFormat>>, )

Called once at the beginning of the frame, before any render passes.

fn begin_pass( &mut self, gpu: &Device, gpu_queue: &Queue, config: &SurfaceConfiguration<Vec<TextureFormat>>, render_pass: &mut RenderPass<'_>, scene_texture_view: &TextureView, )

Called once at the beginning of the render pass.

fn end_pass( &mut self, gpu: &Device, gpu_queue: &Queue, config: &SurfaceConfiguration<Vec<TextureFormat>>, render_pass: &mut RenderPass<'_>, scene_texture_view: &TextureView, )

Called once at the end of the render pass.

fn end_frame( &mut self, gpu: &Device, gpu_queue: &Queue, config: &SurfaceConfiguration<Vec<TextureFormat>>, )

Called once at the end of the frame, after all render passes are complete.
