Empty Array [] won't pass to custom validator

Validator.register('fail_array', function(value, requirement, attribute) { 
    return false;
}, ':attribute Failed');
var fields = {attr: []}
var rules = {attr: 'fail_array'}
new Validator(fields, rules);

This validation will won’t fail. There is use case that I want to check an array should include a value, empty array should fail as well.

var Validator = require('./src/validator');

var validator = new Validator({ users: [] }, { users: 'array|min:1' });
console.log(validator.passes()); // true

In Laravel the above fails the validation rule, this seems like a bug.

I require it… because I need to write code that handles soft deletes, like the following:

Validator.register(
    'requiredArray',
    (value: Vm<any>[], requirement, attribute) => {
        console.log({ value, requirement, attribute })
        return value &&
            value.length > 0 &&
            value.filter(x => x.changeStatus != ChangeStatus.MARKED_FOR_DELETION).length > 0
    },
    'At least 1 :attribute is required'
)
