# Specio::Exception(3pm)

An exception class for type constraint failures

## NAME

Specio::Exception - An exception class for type constraint failures

## VERSION

version 0.53

## SYNOPSIS

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

## 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.

## 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.
