A context manager that allows to register error and exit callbacks.

class datumaro.util.scope.Scope

Bases: object

A context manager that allows to register error and exit callbacks.

on_error_do(callback: Callable, *args, kwargs: Dict[str, Any] | None = None, ignore_errors: bool = False)

on_exit_do(callback: Callable, *args, kwargs: Dict[str, Any] | None = None, ignore_errors: bool = False)

Registers a function to be called on scope exit.
