Enum ThemeSource 

pub enum ThemeSource {
    System(ThemeMode),
    MacOs(ThemeMode),
    Windows(ThemeMode),
    Gnome(ThemeMode),
    Preset(Preset),
    Custom(Box<Theme>),
}

Where the theme comes from.

• System matches the host OS look and is the only source that gets live OS accent/color/font injection (the native default).
• MacOs / Windows / Gnome force a specific platform look on any host (a macOS app can render a Windows menu), rendered as-authored.
• Preset is a built-in non-OS skin; Custom is a fully hand-built Theme.

Variants

System(ThemeMode)

Match the host OS look; System(Auto) (the default) follows light/dark.

MacOs(ThemeMode)

Force the macOS look on any host.

Windows(ThemeMode)

Force the Windows look on any host.

Gnome(ThemeMode)

Force the GNOME/Adwaita look on any host.

Preset(Preset)

A built-in non-OS preset skin.

Custom(Box<Theme>)

A fully custom theme.

Implementations

impl ThemeSource

pub fn injects_system(&self) -> bool

Whether this source should receive live OS injection (accent, menu colors, real system font) — true only for System, i.e. when the caller asked to match their OS. Explicit family / preset / custom themes render exactly as authored.

pub fn forced_family(&self) -> Option<OsFamily>

The OsFamily this source forces, if any — Some only for MacOs / Windows / Gnome; None for System/Preset/Custom.

This is the seam a platform backend uses to pick the right drawer constructor (issue #54): when Some(family), the popup must build its drawer with RasterDrawer::with_forced_theme (pins the target OS’s font) instead of RasterDrawer::new_native (pins the host’s font — correct only for System(..)).

pub fn resolve(&self, host: OsFamily, system_is_dark: bool) -> Theme

Resolve to a concrete Theme, given the host OS family and its live dark/light appearance (both supplied by the platform backend; the pure layer can pass any fixed values for testing). Injection of live OS accent/colors/font is layered on by the backend afterwards (see injects_system).
