What the engine provides to the plugins it loads.

Every method is called from whichever thread the plugin used, at any time from the moment the module initializes until the process ends, so an implementation is a queue push rather than a piece of work.

Required Methods

fn event(&self, module: &str, event: PluginEvent) -> bool

Take an event a module pushed. Returns false when the engine is no longer accepting events, which is what a plugin’s worker thread sees while the app shuts down.

fn log(&self, module: &str, level: LogLevel, message: &str)

Take a diagnostic line from a module.

fn wake(&self)

Ask for another tick, so a queued event is drained without waiting for input.
