=head1 NAME

Wikibase::Datatype::Struct::Value::Monolingual - Wikibase monolingual value structure serialization.

=head1 SYNOPSIS

 use Wikibase::Datatype::Struct::Value::Monolingual qw(obj2struct struct2obj);

 my $struct_hr = obj2struct($obj);
 my $obj = struct2obj($struct_hr);

=head1 DESCRIPTION

This conversion is between objects defined in Wikibase::Datatype and structures
serialized via JSON to MediaWiki.

=head1 SUBROUTINES

=head2 C<obj2struct>

 my $struct_hr = obj2struct($obj);

Convert Wikibase::Datatype::Value::Monolingual instance to structure.

Returns reference to hash with structure.

=head2 C<struct2obj>

 my $obj = struct2obj($struct_hr);

Convert structure of monolingual to object.

Returns Wikibase::Datatype::Value::Monolingual instance.

=head1 ERRORS

 obj2struct():
         Object doesn't exist.
         Object isn't 'Wikibase::Datatype::Value::Monolingual'.

 struct2obj():
         Structure isn't for 'monolingualtext' datatype.
