Struct SharedContext 

pub struct SharedContext {
    pub font_system: Arc<RwLock<FontSystem>>,
    pub swash_cache: Arc<RwLock<SwashCache>>,
    pub viewport: Viewport,
    pub renderer: Renderer,
    pub uniform_bind_group_layout: BindGroupLayout,
}

Shared context containing resources common to all text renderers.

This includes the font system, swash cache, viewport, and projection uniform layout. By sharing these resources, multiple renderers can coexist without duplicating font data.

Fields

font_system: Arc<RwLock<FontSystem>>

The font system containing loaded fonts.

swash_cache: Arc<RwLock<SwashCache>>

Cache for rasterized glyph images.

viewport: Viewport

Current viewport configuration.

renderer: Renderer

Low-level renderer for creating GPU resources.

uniform_bind_group_layout: BindGroupLayout

Bind group layout for projection matrix uniform.

Implementations

impl SharedContext

pub fn new( context: Arc<GraphicsContext>, font_system: Arc<RwLock<FontSystem>>, ) -> Self

Create a new shared context.

Arguments

• context - Graphics context for GPU resource creation
• font_system - Arc-wrapped font system to share between renderers

pub fn set_viewport(&mut self, viewport: Viewport)

Set the viewport.

pub fn scale_factor(&self) -> f32

Get the current scale factor.
