Convenience facilities for managing exceptions.
Project description
Presents:
return_exc_info: call supplied function with arguments, return either (function_result, None) or (None, exc_info) if an exception was raised.
@returns_exc_info, a decorator for a function which wraps in it return_exc_info.
@noexc, a decorator for a function whose exceptions should never escape; instead they are logged. The initial use case was inside logging functions, where I have had a failed logging action abort a program. Obviously this is a decorator which should see very little use.
@noexc_gen, a decorator for generators with similar effect to @noexc for ordinary functions.
