    print $_, "\n" for @{ $type->values };
```

# [DESCRIPTION](#DESCRIPTION)

This is a specialized type constraint class for types which require a string that matches one of a list of values.

# [API](#API)

This class provides all of the same methods as Specio::Constraint::Simple, with a few differences:

## [Specio::Constraint::Enum->new( ... )](#Specio::Constraint::Enum)

The "parent" parameter is ignored if it passed, as it is always set to the "Str" type.

The "inline\_generator" and "constraint" parameters are also ignored. This class provides its own default inline generator subroutine reference.

Finally, this class requires an additional parameter, "values". This must be a an arrayref of valid strings for the type.

## [$enum->values](#$enum)

Returns an array reference of valid values for the type.

# [ROLES](#ROLES)

This class does the Specio::Constraint::Role::Interface and Specio::Role::Inlinable roles.
