NAME

Throwable::Error - an easy-to-use class for error objects

CONTENTS

VERSION

version 0.200013

SYNOPSIS



  package MyApp::Error;
  # NOTE: Moo can also be used here instead of Moose
  use Moose;
  extends Throwable::Error;

  has execution_phase => (
    is  => ro,
    isa => MyApp::Phase,
    default => startup,
  );



...and in your app...



  MyApp::Error->throw("all communications offline");

  # or...

  MyApp::Error->throw({
    message         => "all communications offline",
    execution_phase => shutdown,
  });



DESCRIPTION

Throwable::Error is a base class for exceptions that will be thrown to signal errors and abort normal program flow. Throwable::Error is an alternative to Exception::Class, the features of which are largely provided by the Moo object system atop which Throwable::Error is built.

Throwable::Error performs the Throwable and StackTrace::Auto roles. That means you can call throw on it to create and throw an error object in one call, and that every error object will have a stack trace for its creation.

ATTRIBUTES

    message

This attribute must be defined and must contain a string describing the error condition. This string will be printed at the top of the stack trace when the error is stringified.

    stack_trace

This attribute, provided by StackTrace::Auto, will contain a stack trace object guaranteed to respond to the as_string method. For more information about the stack trace and associated behavior, consult the StackTrace::Auto docs.

METHODS

    as_string

This method will provide a string representing the error, containing the error’s message followed by the its stack trace.
