This function can handle text containing wide characters and ANSI escape codes.

Note: to pad to a certain character length instead of column width (note that
wide characters like Chinese can have width of more than 1 column in terminal),
you can turn of `mb` option even when your text contains wide characters.

=head1 FUNCTIONS


=head2 rpad

Usage:

 rpad(%args) -> [status, msg, payload, meta]

Pad text to the right until a certain column width.

This function can handle text containing wide characters and ANSI escape codes.

Note: to pad to a certain character length instead of column width (note that
wide characters like Chinese can have width of more than 1 column in terminal),
you can turn of C<mb> option even when your text contains wide characters.

This function is not exported.

Arguments ('*' denotes required arguments):

=over 4

=item * B<ansi> => I<bool> (default: 0)

Whether to handle ANSI escape codes.

=item * B<char> => I<str> (default: " ")

Character to use for padding.

Character should have column width of 1. The default is space (ASCII 32).

=item * B<in> => I<array>

Input stream (e.g. array or filehandle).

=item * B<mb> => I<bool> (default: 0)

Whether to handle wide characters.

=item * B<out> => I<any>

Output stream (e.g. array or filehandle).

=item * B<trunc> => I<bool> (default: 0)

Whether to truncate text wider than specified width.

=item * B<width>* => I<int>

=back

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code
(200 means OK, 4xx caller error, 5xx function error). Second element
(msg) is a string containing error message, or 'OK' if status is
200. Third element (payload) is optional, the actual result. Fourth
element (meta) is called result metadata and is optional, a hash
that contains extra information.

Return value:  (any)
