NAME ^

Specio::Exception - A Throwable::Error subclass for type constraint failures

VERSION ^

version 0.16

DESCRIPTION ^

This exception class is thrown by Specio when a type check fails. It emulates the Throwable::Error API, but doesn't use that module to avoid adding a dependency on Moo.

DESCRIPTION ^

  use Try::Tiny;

  try {
      $type->validate_or_die($value);
  }
  catch {
      if ( $_->isa('Specio::Exception') ) {
          print $_->message, "\n";
          print $_->type->name, "\n";
          print $_->value, "\n";
      }
  };

API ^

This class provides the following methods:

$exception->message

The error message associated with the exception.

$exception->stack_trace

A Devel::StackTrace object for the exception.

$exception->type

The type constraint object against which the value failed.

$exception->value

The value that failed the type check.

$exception->as_string

The exception as a string. This includes the method and the stack trace.

OVERLOADING ^

This class overloads stringification to call the as_string method.

SUPPORT ^

Bugs may be submitted through the RT bug tracker (or bug-specio@rt.cpan.org).
