Fonts
Fission design-system codegen can embed font files into the generated Rust design-system type.
Type | Meaning |
|---|---|
DesignAssetManifest | Generated manifest with logos and fonts. |
DesignFontAsset | Metadata for a font declared in the DSP. |
PackagedFont | Embedded font bytes plus family, weight, style, format, and axes. |
FontVariationAxis | Variation axis default for variable fonts. |
PackagedFontStyle | Normal or italic style metadata. |
DesignSystem::font_faces() | Runtime entry point shells use to register packaged fonts. |
DesktopApp::<AppState, _>::new(App)
.with_design_system::<AppDesignSystem>(DesignMode::Light)
.run()
The shell registers AppDesignSystem::font_faces() before rendering so text can resolve the declared family without relying on installed system fonts.

Ready to use today. Widget APIs are expected to remain stable; some runtime and shell APIs may change before 1.0.0.
