Enum TrayIconSource 

#[repr(C, u8)]
pub enum TrayIconSource {
    None,
    Rgba(TrayIconImageVec),
    Named(AzString),
}

Where a tray icon’s pixels come from.

Variants

None

No icon. Most desktops render this as an invisible item, so it is almost never what you want.

Rgba(TrayIconImageVec)

Explicit RGBA bitmaps, ideally at several sizes so each platform can pick - see TrayIconData::best_icon.

Only needed for an icon that genuinely is not in a pack - typically one generated at runtime, since the icon registry is frozen once the provider is shared (App::run consumes the handle).

Named(AzString)

An icon spec - exactly the string an <icon> node takes: a bare name ("settings"), a pack-qualified name ("mypack:logo"), or a comma-separated fallback list ("mypack:logo, settings").

This is the preferred form, for two reasons.

It resolves through the SAME registry and resolver <icon> DOM nodes use, so anything registered there works with no tray-specific icon path: Material Icons (the default pack), an image pack loaded from a ZIP, or a custom resolver. Because resolution yields a StyledDom which is then rendered, an icon can be anything expressible as a DOM: a font glyph, a bitmap, later an SVG or an emoji.

And a spec can be rendered at ANY size on demand, which a fixed bitmap cannot: a tray needs the same icon at several sizes and cannot know them up front (Windows re-asks at every taskbar DPI: 16/20/24/32; macOS wants 18pt, which is 36px on a 2x display; SNI publishes an array).
