        name     => [[qw/LENGTH 5 20/]],
        password => [[qw/LENGTH 5/]],
    );

NOT_IN


    $validator->check(
        new_user => [[NOT_IN => \@existing_users]]
    );



The parameter does not belong to the list of values.

MATCH


    use MyApp::Util qw/is_foo/;

    $validator->check(
        foo => [[MATCH => \&is_foo ]],
        bar => [[MATCH => sub { $_[0] eq foo } ]],
    );



Check parameter using callback. Callback takes parameter as first argument, should return true/false.

FILTER


    $validator->check(
        foo => [[FILTER => trim], INT],
        bar => [[FILTER => sub { $_[0] . @example.com } ], EMAIL],

FILTER is special constraint. It does not check the value and simply filter. trim is only pre-defined. You can also pass a callback. Callback takes parameter as first argument, should return filtered value.
