List::UtilsBy::XS - XS implementation of List::UtilsBy

use List::UtilsBy::XS qw(sort_by);

sort_by { $_->{foo} } @hash_ref_list

You can use those functions same as List::UtilsBy ones, but some functions have limitation. See LIMITATION section.

List::UtilsBy::XS is XS implementation of List::UtilsBy. Functions are more fast than original ones.

Same as List::UtilsBy

List::UtilsBy::XS implements following functions.

• sort_by
• nsort_by
• rev_sort_by
• rev_nsort_by
• max_by (alias nmax_by)
• min_by (alias nmin_by)
• uniq_by
• partition_by
• count_by
• zip_by
• unzip_by
• extract_by
• weighted_shuffle_by
• bundle_by

Some functions are implemented by lightweight callback API. sort_by, rev_sort_by, nsort_by, rev_nsort_by, min_by, max_by, nmin_by, nmax_by, uniq_by, partion_by, count_by, extract_by, weighted_shuffle_by are limited some features.

Limitations are:

List::UtilsBy localizes $_ in the code block, but List::UtilsBy::XS doesn't localize it and it is only alias same as map, grep. So you should not modify $_ in callback subroutine.

You can access argument as only $_ and cannot access as @_, $_[n].
