Struct ThemeRegistry 

pub struct ThemeRegistry { /* private fields */ }

Built-in + user themes combined. User themes override built-ins of the same name (with a warning). When two user files declare the same name, the first one loaded wins and the later one is warned + skipped — matches docs/specs/theming.md §Edge cases. Files are processed in filename-sorted order, so “first” means alphabetically first.

Implementations

impl ThemeRegistry

pub fn with_built_ins() -> Self

Start with the compiled-in themes; no file I/O.

pub fn with_user_themes(self, dir: &Path, warn: impl FnMut(&str)) -> Self

Load every *.toml in dir and merge into the registry. One bad file never aborts the walk; each parse error emits a diagnostic via warn and the file is skipped. Files are processed in filename-sorted order. A user theme whose name collides with a built-in replaces the built-in (with a warning); a user theme whose name collides with an already- loaded user theme is warned + skipped — per the spec’s “first-user-theme-found wins” rule.

pub fn lookup(&self, name: &str) -> Option<&Theme>

Look up a theme by its registered name. Returns None for unknown names so resolve_theme can warn + fall back.

pub fn iter(&self) -> impl Iterator<Item = &RegisteredTheme>

Enumerate registered themes in registration order: built-ins first (in compile-time order), then user themes sorted by filename.
