Usage

Here's a quick example of how to use fluent_validator:

from fluent_validator import validate, validate_all

# Validate a single value
validate(10).not_is_none().greater_than(5).not_equal(40)

# Or validate multiple values
validate_all(10, 100).not_is_none().greater_than(5).not_equal(40)

Available Validations

fluent_validator offers a wide range of validations to suit your needs.

Notably, all validations have a corresponding negative form. Simply prefix the method with not_.

For example, the negative of is_none() is not_is_none().
