Struct FlexibleTextRenderer 

pub struct FlexibleTextRenderer {
    font_system: Arc<Mutex<FontSystem>>,
    swash_cache: SwashCache,
    atlas: TextAtlas,
    viewport: Viewport,
    text_renderer: TextRenderer,
    device: Device,
    queue: Queue,
    resolution: Resolution,
}

Wgpu glyph rasterizer wrapping glyphon’s pipeline.

Owns the glyphon-side GPU resources (atlas, viewport, renderer, swash cache) plus a shared handle to the font system used by the paired FlexibleTextEngine.

Fields

font_system: Arc<Mutex<FontSystem>>

swash_cache: SwashCache

atlas: TextAtlas

viewport: Viewport

text_renderer: TextRenderer

device: Device

queue: Queue

resolution: Resolution

Implementations

impl FlexibleTextRenderer

pub fn new( app: &Application, format: TextureFormat, font_system: Arc<Mutex<FontSystem>>, ) -> Self

Build the renderer for a target color format.

format MUST match the format of every TextureView later passed to Self::draw. Multisample is fixed at 1× and depth stencil is unused — glyphon writes directly to the color attachment.

pub fn set_resolution(&mut self, width_px: u32, height_px: u32)

Update the rasterization resolution. Call whenever the target view’s dimensions change.

pub fn draw( &mut self, target_view: &TextureView, layouts: &[(&FlexibleTextLayout, Vec2, Color)], clear: bool, )

Stage layouts and emit draw calls into a fresh render pass on target_view. clear chooses whether to clear the target before drawing — set false when compositing on top of existing content.

Each entry is (layout, position_ndc, color):

• position_ndc is the top-left of the layout box in NDC ([-1, +1]). It’s converted to glyphon pixel space using the current resolution.
• color provides the default per-glyph color.

pub fn trim_atlas(&mut self)

Trim atlas LRU entries that haven’t been referenced since the last call. Call between frames to keep the atlas bounded.

Trait Implementations

impl Debug for FlexibleTextRenderer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
