=head1 NAME

Message::Passing::Output::ZeroMQ - output messages to ZeroMQ.

=head1 SYNOPSIS

    use Message::Passing::Output::ZeroMQ;

    my $logger = Message::Passing::Output::ZeroMQ->new;
    $logger->consume({data => { some => 'data'}, '@metadata' => 'value' });

    # Or see Log::Dispatch::Message::Passing for a more 'normal' interface to
    # simple logging.

    # Or use directly on command line:
    message-passing --input STDIN --output ZeroMQ --output_options \
        '{"connect":"tcp://192.168.0.1:5552"}'
    {"data":{"some":"data"},"@metadata":"value"}

=head1 DESCRIPTION

A L<Message::Passing> ZeroMQ output class.

Can be used as part of a chain of classes with the L<message-passing> utility, or directly as
a logger in normal perl applications.

=head1 ATTRIBUTES

See L<Message::Passing::ZeroMQ/CONNECTION ATTRIBUTES>.

=head1 METHODS

=head2 consume ($msg)

Sends a message, as-is. This means that you must have encoded the message to a string before
sending it. The C<message-pass> utility will do this for you into JSON, or you can
do it manually as shown in the example in L<Message::Passing::ZeroMQ>.
