# Specio::Constraint::Structured(3pm)

A class which represents structured constraints

## NAME

Specio::Constraint::Structured - A class which represents structured constraints

## VERSION

version 0.53

## SYNOPSIS

```
    my $tuple = t('Tuple');
    my $tuple_of_str_int = $tuple->parameterize( of => [ t('Str'), t('Int') ] );
    my $parent = $tuple_of_str_int->parent; # returns Tuple
    my $parameters = $arrayref_of_int->parameters; # returns { of => [ t('Str'), t('Int') ] }
```

## DESCRIPTION

This class implements the API for structured types.

## API

This class implements the same API as Specio::Constraint::Simple, with a few additions.

### Specio::Constraint::Structured-\>new(...)

This class's constructor accepts two additional parameters:

- •

  parent

  This should be the Specio::Constraint::Structurable object from which this object was created.

  This parameter is required.

- •

  parameters

  This is the hashref of parameters for the structured type. These are the parameters returned by the `"Structurable"` type's `"parameterization_args_builder"`. The exact form of this hashref will vary for each structured type.

  This parameter is required.

### $type-\>parameters

Returns the hashref that was passed to the constructor.
