NAME

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

CONTENTS

VERSION

version 0.12

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:

CW$exception->message()

The error message associated with the exception.

CW$exception->stack_trace()

A Devel::StackTrace object for the exception.

CW$exception->type()

The type constraint object against which the value failed.

CW$exception->value()

The value that failed the type check.

CW$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.
