=head1 NAME

Data::Sah::Coerce::perl::To_datenotime::From_str::iso8601 - Coerce datenotime from (a subset of) ISO8601 string

=head1 VERSION

This document describes version 0.051 of Data::Sah::Coerce::perl::To_datenotime::From_str::iso8601 (from Perl distribution Data-Sah-Coerce), released on 2021-10-18.

=head1 SYNOPSIS

To use in a Sah schema:

 ["datenotime",{"x.perl.coerce_rules"=>["From_str::iso8601"]}]

=head1 DESCRIPTION

This rule coerces datenotime from a subset of ISO8601 string. Currently only the
following formats are accepted:

 "YYYY-MM-DD"            ; # date (local time), e.g.: 2016-05-13

=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.
