NAME
List::UtilsBy::XS - XS implementation of List::UtilsBy
SYNOPSIS
use List::UtilsBy::XS qw(sort_by);
sort_by { $_->{foo} } @hash_ref_listYou 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].
