pub fn from_system() -> Result<(Theme, ResolvedThemeVariant, bool)>Expand description
Detect the OS theme and convert it to a gpui-component Theme in one call.
Combines SystemTheme::from_system()
with to_theme() using the system-detected name and dark-mode preference.
Returns both the gpui Theme and the ResolvedThemeVariant so callers can
access per-widget metrics that the flat ThemeColor cannot represent.
Ownership note (Issue 19/31): this function takes ownership of the
SystemTheme’s active variant. The non-active variant (light when dark
is active, or vice versa) is dropped. If you need both variants, use
SystemTheme::from_system() directly and call to_theme() on each.
Performance note: SystemTheme::from_system() resolves both light
and dark variants before this function picks one. If you only need one
variant and want to avoid the cost of resolving both, use
SystemTheme::from_system() directly and resolve only the variant you need.
§Errors
Returns an error if the platform theme cannot be read (e.g., unsupported platform, missing desktop environment).
§Examples
let (theme, resolved, is_dark) = native_theme_gpui::from_system()?;
