NAME

Data::Sah::Filter::perl::Array::check_uniqnum - Check that an array has unique elements, using List::Util's uniqnum()

VERSION

This document describes version 0.025 of Data::Sah::Filter::perl::Array::check_uniqnum (from Perl distribution Data-Sah-Filter), released on 2024-07-17.

SYNOPSIS

Using in Sah schema's prefilters (or postfilters) clause


            

              
              
["array","prefilters",[["Array::check_uniqnum"]]]

Using with Data::Sah:


            

              
              
use Data::Sah qw(gen_validator);
my $schema = ["array","prefilters",[["Array::check_uniqnum"]]];
my $validator = gen_validator($schema);
if ($validator->($some_data)) { print 'Valid!' }

Using with Data::Sah:Filter directly:


            

              
              
use Data::Sah::Filter qw(gen_filter);
my $filter = gen_filter([["Array::check_uniqnum"]]);
# $errmsg will be empty/undef when filtering succeeds
my ($errmsg, $filtered_value) = $filter->($some_data);

Sample data and filtering results


            

              
              
[] # valid, unchanged
[1,2] # valid, unchanged
[1,2,"1.0"] # INVALID (Array has duplicate number(s): "1.0"), becomes undef
[] # filtered with args {reverse=>1}, INVALID (Array does not have duplicate number(s)), becomes undef
[1,2] # filtered with args {reverse=>1}, INVALID (Array does not have duplicate number(s)), becomes undef
[1,2,"1.0"] # filtered with args {reverse=>1}, valid, unchanged

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:


            

              
              
% prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
