## NAME
    [Moose::Exception](https://www.chedong.com/phpMan.php/perldoc/Moose%3A%3AException/markdown) - Superclass for Moose internal exceptions

## VERSION
    version 2.2200

## DESCRIPTION
    This class contains attributes which are common to all Moose internal exception classes.

## WARNING WARNING WARNING
    If you're writing your own exception classes, you should instead prefer the Throwable role or
    the [Throwable::Error](https://www.chedong.com/phpMan.php/perldoc/Throwable%3A%3AError/markdown) superclass - this is effectively a cut-down internal fork of the latter,
    and not designed for use in user code.

    Of course if you're writing metaclass traits, it would then make sense to subclass the relevant
    Moose exceptions - but only then.

## METHODS
  $exception->message
    This attribute contains the exception message.

    Every subclass of [Moose::Exception](https://www.chedong.com/phpMan.php/perldoc/Moose%3A%3AException/markdown) is expected to override "_build_message" method in order to
    construct this value.

  $exception->trace
    This attribute contains the stack trace for the given exception. It returns a [Devel::StackTrace](https://www.chedong.com/phpMan.php/perldoc/Devel%3A%3AStackTrace/markdown)
    object.

  $exception->as_string
    This method returns a stringified form of the exception, including a stack trace. By default,
    this method skips Moose-internal stack frames until it sees a caller outside of the Moose core.
    If the "MOOSE_FULL_EXCEPTION" environment variable is true, these frames are included.
