man Throwable::Error (3): an easy-to-use class for error objects

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.
