    );

Check parameter match the argument or not.

        sex => [[CHOICE => qw/male female/]]
    );

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.
