If no context is found, a new ``ClientContext`` object is created. It mainly ensures the context variable is reset to the previous value once the executed code returns. Example usage: def my_feature(): with start_as_current_context(): register_feature_id('MY_FEATURE') pass :type ctx: ClientContext :param ctx: The client context object to set as the new context variable. If not provided, the current or a new context variable is used.

This is just syntactic sugar to avoid indenting existing code under the context manager. Example usage: @with_current_context(partial(register_feature_id, 'MY_FEATURE')) def my_feature(): pass :type hook: callable :param hook: A callable that will be invoked within the scope of the ``start_as_current_context`` context manager. cstfdd}|S)NcsBtr |i|WdS1swYdSN)r)argskwargs)funchookrrwrappervs  $z8with_current_context..decorator..wrapperr)r#r%r$)r#r decoratorusz'with_current_context..decoratorr)r$r'rr&rwith_current_contextds  r(r )r contextlibr contextvarsrcopyr dataclassesrr functoolsrr rrrrrr(rrrrs
