NAME ^

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

SYNOPSIS ^

  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.

DESCRIPTION ^

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

FUNCTIONS ^

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

LIMITATIONS ^

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:

Don't change argument $_ in code block

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.

Can't access to arguments as @_ in code block

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