=over 4

=item C<< parse_iter_from_io( $fh ) >>

the L<IO::Handle> object C<< $fh >>.

=item C<< parse_iter_from_bytes( $data ) >>

Returns an L<Attean::API::Iterator> that result from parsing the data read from
the UTF-8 encoded byte string C<< $data >>.

=back

=head1 METHODS

This role provides default implementations of the following methods:

=over 4

=item C<< parse_cb_from_io( $fh ) >>

Calls the C<< $parser->handler >> function once for each object that result
from parsing the data read from the L<IO::Handle> object C<< $fh >>.

=item C<< parse_cb_from_bytes( $data ) >>

Calls the C<< $parser->handler >> function once for each object that result
from parsing the data read from the UTF-8 encoded byte string C<< $data >>.

=item C<< parse_list_from_io( $fh ) >>

Returns a list of all objects that result from parsing the data read from the
L<IO::Handle> object C<< $fh >>.

=item C<< parse_list_from_bytes( $data ) >>

Returns a list of all objects that result from parsing the data read from the
UTF-8 encoded byte string C<< $data >>.
