# ABSTRACT: perl's type handler for type "hash"
__END__
=pod
=encoding UTF-8
=head1 NAME
Data::Sah::Compiler::perl::TH::hash - perl's type handler for type "hash"
=head1 VERSION
This document describes version 0.917 of Data::Sah::Compiler::perl::TH::hash (from Perl distribution Data-Sah), released on 2024-02-16.
=for Pod::Coverage ^(clause_.+|superclause_.+)$
=head1 HOMEPAGE
Please visit the project's homepage at L<https://metacpan.org/release/Data-Sah>.
=head1 SOURCE
Source repository is at L<https://github.com/perlancar/perl-Data-Sah>.
=head1 AUTHOR
perlancar <[email protected]>
=head1 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 L<Dist::Zilla>,
L<Dist::Zilla::PluginBundle::Author::PERLANCAR>,
L<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.

=head1 BUGS
Please report any bugs or feature requests on the bugtracker website L<https://rt.cpan.org/Public/Dist/Display.html?Name=Data-Sah>
When submitting a bug or request, please include a test-file or a
patch to an existing test-file that illustrates the bug or desired
feature.
