Implementations

impl Theme

pub fn from_cosmic() -> Option<Self>

Create a theme from COSMIC desktop configuration

This provides native integration with COSMIC’s theming system, automatically matching dark/light mode and accent colors.

COSMIC uses a layered color system with guaranteed contrast:

• Container level (base/on): For surfaces - on contrasts with base
• Component level (component.base/on): For buttons/inputs inside containers

The overlay popup implements a “primary” container pattern:

• primary.base for the card background
• primary.on for text (designed for contrast on primary.base)
• primary.component.* for badge elements (interactive-like)
• accent.* for highlights and matched states

pub fn from_config(config: &Config) -> Self

Create a theme from user configuration

This is used when COSMIC theme is not available or when user has explicit color overrides in their config.
