Struct RendererCore 

pub struct RendererCore { /* private fields */ }

RendererCore replays display lists on a host-owned wgpu device.

Hosts normally use the valo crate’s Context instead. This type is the GPU core that context wraps: it owns caches and pipelines, and holds no application content of its own.

Implementations

impl RendererCore

pub fn new(device: Device, queue: Queue) -> Self

new creates a renderer from a host-owned device and queue.

pub fn images(&mut self) -> &mut ImageStore

images returns the image store used for uploads and sampling.

pub fn device(&self) -> &Device

device returns the device used by this renderer.

pub fn set_text_tiers(&mut self, tiers: TextTiers)

set_text_tiers controls how text is rendered across font-size ranges.

Valo uses bitmap masks below sdf_min, SDF below path_min, and outlines above it. The defaults suit normal use; override them only for specialized scaling or zoom behavior.

pub fn set_hide_missing_glyphs(&mut self, hide: bool)

set_hide_missing_glyphs controls whether unresolved characters render blank.

By default, unresolved characters render the font’s .notdef glyph, usually a “tofu” box. This is common when CJK fallback fonts are missing. Use valo_text::FontDemand to detect characters hidden by this option.

pub fn set_text_raster_hold(&mut self, held: bool)

set_text_raster_hold allows existing text rasters to stand in for missing sizes.

This applies to bitmap-mask and SDF text, not vector outlines. It is useful during rapid zooming: enable it while the gesture is active and clear it afterward so the next frame renders sharply.

pub fn set_raster_hold(&mut self, held: bool)

set_raster_hold allows cached display-list textures to be reused at any scale.

This is useful during rapid zooming: enable it when the gesture starts and clear it when the view settles so caches refill at the final scale.

pub fn render( &mut self, dl: &DisplayList, target: &RenderTarget<'_>, ) -> RenderStats

render draws a display list into a target and returns frame statistics.

Each call submits one command buffer.

pub fn memory_report(&self) -> MemoryReport

memory_report returns resource counts and estimated GPU memory usage.

The counters feature adds the counters reported by wgpu.
