=head1 NAME
Specio::Constraint::Enum - A class for constraints which require a string matching one of a set of values
=head1 VERSION
version 0.42
=head1 SYNOPSIS
my $type = Specio::Constraint::Enum->new(...);
print $_, "\n" for @{ $type->values };
=head1 DESCRIPTION
This is a specialized type constraint class for types which require a string
that matches one of a list of values.
=head1 API
This class provides all of the same methods as L<Specio::Constraint::Simple>,
with a few differences:
=head2 Specio::Constraint::Enum->new( ... )
The C<parent> parameter is ignored if it passed, as it is always set to the
C<Str> type.
The C<inline_generator> and C<constraint> parameters are also ignored. This
class provides its own default inline generator subroutine reference.
Finally, this class requires an additional parameter, C<values>. This must be a
an arrayref of valid strings for the type.
=head2 $enum->values
Returns an array reference of valid values for the type.
=head1 ROLES
This class does the L<Specio::Constraint::Role::Interface> and
L<Specio::Role::Inlinable> roles.
=head1 SUPPORT
Bugs may be submitted at L<https://github.com/houseabsolute/Specio/issues>.
I am also usually active on IRC as 'autarch' on C<irc://irc.perl.org>.
