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. .PP Throwable::Error performs the Throwable and StackTrace::Auto roles. That means you can call \f(CW\*(C`throw\*(C'\fR 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. .SH "PERL VERSION" .IX Header "PERL VERSION" This library should run on perls released even a long time ago. It should work on any version of perl released in the last five years. .PP Although it may work on older versions of perl, no guarantee is made that the minimum required version will not be increased. The version may be increased for any reason, and there is no promise that patches will be accepted to lower the minimum required perl. .SH "ATTRIBUTES" .IX Header "ATTRIBUTES" .SS "message" .IX Subsection "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. .SS "stack_trace" .IX Subsection "stack_trace" This attribute, provided by StackTrace::Auto, will contain a stack trace object guaranteed to respond to the \f(CW\*(C`as_string\*(C'\fR method. For more information about the stack trace and associated behavior, consult the StackTrace::Auto docs. .SH "METHODS" .IX Header "METHODS" .SS "as_string" .IX Subsection "as_string" This method will provide a string representing the error, containing the error's message followed by the its stack trace. .SH "AUTHORS" .IX Header "AUTHORS" .IP "\(bu" 4 Ricardo \s-1SIGNES\s0 .IP "\(bu" 4 Florian Ragwitz .SH "COPYRIGHT AND LICENSE" .IX Header "COPYRIGHT AND LICENSE" This software is copyright (c) 2022 by Ricardo \s-1SIGNES.\s0 .PP This is free software; you can redistribute it and/or modify it under the same terms as the Perl 5 programming language system itself.
