Struct ThemeManager 

pub struct ThemeManager { /* private fields */ }

Manages the active theme and optionally watches a theme file for changes.

Implementations

impl ThemeManager

pub fn new(theme: Theme) -> Self

Create a new manager with the given theme.

pub fn dark() -> Self

Create a manager that starts with the default dark theme.

pub fn light() -> Self

Create a manager that starts with the default light theme.

pub fn watch_file(&mut self, path: impl Into<PathBuf>) -> Result<()>

Start watching a theme file for changes.

The file format is auto-detected from the extension (.toml or .json). On each call to ThemeManager::check_reload, the file’s mtime is compared to the last known value; if it changed, the theme is reloaded.

pub fn theme(&self) -> Theme

Get a clone of the current theme.

pub fn theme_handle(&self) -> Arc<RwLock<Theme>>

Get a handle to the shared theme lock.

pub fn set_theme(&self, theme: Theme)

Replace the active theme.

pub fn set_theme_by_name(&self, name: &str) -> bool

Set the active theme by name (“dark” or “light”).

Returns true if the name was recognized.

pub fn check_reload(&mut self) -> bool

Check if the watched file has changed and reload if so.

Call this periodically (e.g. once per event-loop tick). Returns true if the theme was reloaded.

pub fn set_poll_interval(&mut self, interval: Duration)

Set the polling interval for file watching (default 1s).
