# MooseX::TraitFor::Meta::TypeConstraint::Mooish(3pm)

Handle Moo-style constraints

## NAME

MooseX::TraitFor::Meta::TypeConstraint::Mooish - Handle Moo-style constraints

## VERSION

This document describes version 0.001 of MooseX::TraitFor::Meta::TypeConstraint::Mooish - released March 12, 2015 as part of MooseX-Meta-TypeConstraint-Mooish.

## SYNOPSIS

This trait implements the functionality described in MooseX::Meta::TypeConstraint::Mooish, and you, dear reader, are encouraged to read about it over there.  Here we simply document the nuts and bolts.

## DESCRIPTION

```
    # determining where this goes is left as an exercise for the reader
    with 'MooseX::TraitFor::Meta::TypeConstraint::Mooish';
```

## ATTRIBUTES

### original\_constraint

The original constraint CodeRef is stashed away here.

### mooish

If true, the constraint should be considered written in the style of Moo constraints; that is, if an exception is thrown the constraint is considered to have failed; otherwise it passes.  Return values are ignored.

Default is true.

## METHODS

### original\_constraint()

Reader for the "original\_constraint" attribute; returns the original constraint as passed to **new()**.

### has\_original\_constraint()

Predicate for the "original\_constraint" attribute.

### mooish()

Reader for the "mooish" attribute.

### compile\_type\_constraint

If "mooish" is true, we wrap the "original\_constraint" in a sub that translates Moo behaviors (die on fail; otherwise success) to Moose::Meta::TypeConstraint expectations (false on fail; true on success).

We stash the original constraint in "original\_constraint" (surprise!), and set the constraint attribute to the wrapped constraint.

### create\_child\_type

Subtypes created here are not mooish, unless an explicit `"mooish ="` 1\> is passed.
