AstBundle class

A transportable unit containing an entry point and all required modules.

AstBundle is the primary distribution format for pre-parsed D4rt scripts. It encapsulates one or more SCompilationUnit modules that can be executed by D4rtRunner without requiring the Dart analyzer.

final bundle = AstBundle(
  entryPointUri: 'bin/main.dart',
  modules: {'bin/main.dart': mainAst, 'lib/utils.dart': utilsAst},
);
bundle.saveToFile('my_script.ast');

// Load and execute
final loaded = AstBundle.fromFile('my_script.ast');
final runner = D4rtRunner();
runner.execute(ast: loaded.entryPoint);
