Function as rule

[nikalosa]

Enhance validator to read rule as a function

Example:

from validator import validate

def func_age(x):
    return x >= 18

# Dummy Checker
def func_mail(x):
    return "@" in x

rules = {"name": lambda x: len(x) > 1000,
         "age": func_age,
         "mail": func_mail}

req = {"name": "Jon",
       "age": 30,
       "mail": "JonDoe@gmail.com"}

validate(req, rules)
