Struct ThemeRegistry 

pub struct ThemeRegistry { /* private fields */ }

All themes known to an application: the built-in ones plus any loaded from disk.

A loaded file with the same id as a built-in theme replaces it.

Implementations

impl ThemeRegistry

pub fn builtin() -> Self

A registry holding the built-in themes.

pub fn add_source(&mut self, id: &str, file: &str, text: &str) -> bool

Adds or replaces theme id from TOML text. Returns whether the file was usable.

pub fn load_dir(&mut self, dir: &Path) -> Result<()>

Loads every *.toml file in dir; the file stem is the theme id.

Errors

Returns the I/O error when the directory cannot be read. A file that cannot be read is skipped and reported in the diagnostics.

pub fn list(&self) -> Vec<(String, String)>

(id, display name) of every theme, sorted by id; for a settings screen.

pub fn diagnostics(&self) -> &[Diagnostic]

Problems found while loading files.

pub fn resolve(&self, id: &str) -> Resolved

Resolves theme id through its extends chain.

pub fn resolve_or_default(&self, id: &str) -> (Theme, Vec<Diagnostic>)

Resolves theme id, falling back to the pristine built-in default theme when id cannot be built. Diagnostics explain why a fallback happened.
