NAME

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

VERSION

version 0.10

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.
