Struct Theme 

pub struct Theme { /* private fields */ }

A parsed Helix-compatible theme.

Contains resolved Styles keyed by scope name (e.g. "ui.text").

Implementations

impl Theme

pub fn empty() -> Self

Create an empty theme with no styles. Useful as a placeholder for built-in / fallback theme structs.

pub fn name(&self) -> &str

The theme name (filename stem, e.g. "catppuccin_mocha").

pub fn get(&self, scope: &str) -> Style

Look up a style by exact scope name. Returns Style::default() if not found.

pub fn try_get(&self, scope: &str) -> Option<Style>

Look up a style with dot-delimited fallback: ui.text.focus → ui.text → ui → none.

pub fn try_get_exact(&self, scope: &str) -> Option<Style>

Look up a style by exact scope name with no fallback.

pub fn styles(&self) -> &HashMap<String, Style>

Borrow the full styles map.

pub fn role(&self, role: ThemeRole) -> Style

Resolve the first usable style for a typed theme role.

pub fn style_from_scopes(&self, scopes: &[&str]) -> Style

Resolve the first usable style across a fallback list of Helix scopes.

Later scopes patch earlier missing fields only; lookup stops once both foreground and background are known.
