=head1 NAME

Data::Sah::Coerce::perl::To_duration::From_str::human - Coerce duration from human notation string (e.g. "2 days 10 hours", "3h")

=head1 SYNOPSIS

To use in a Sah schema:

 ["duration",{"x.perl.coerce_rules"=>["From_str::human"]}]

=head1 DESCRIPTION

The human notation is parsed using L<Time::Duration::Parse::AsHash>.

=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>, and sometimes one or two other
Dist::Zilla plugin and/or Pod::Weaver::Plugin. 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-Coerce>

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.
