NAME

version 0.102080SYNOPSIS
package MyApp::Error; use Moose; extends 'Throwable::Error'; has execution_phase => ( is => 'ro', isa => 'MyApp::Phase', default => 'startup', );

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 Moose 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 n 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.AUTHORS
