An extremely flexible and configurable data model conversion library.

📑 [Documentation](https://adaptix.readthedocs.io/)

## TL;DR

Install
```bash
pip install adaptix
```

Use
```python
from dataclasses import dataclass

from adaptix import Retort


@dataclass
class Book:
    title: str
    price: int
    author: str = "Unknown author"


data = {
    "title": "Fahrenheit 451",
    "price": 100,
}

# Retort is meant to be global constant or just one-time created
retort = Retort()

book = retort.load(data, Book)
assert book == Book(title="Fahrenheit 451", price=100)
assert retort.dump(book) == data
```

## Use cases

* Validation and transformation of received data for your API.
* Config loading/dumping via codec that produces/takes dict.
* Storing JSON in a database and representing it as a model inside the application code.
* Creating API clients that convert a model to JSON sending to the server.
* Persisting entities at cache storage.
* Implementing fast and primitive ORM.

## Advantages

* Sane defaults for JSON processing, no configuration is needed for simple cases.
* Separated model definition and rules of conversion
  that allow preserving [SRP](https://blog.cleancoder.com/uncle-bob/2014/05/08/SingleReponsibilityPrinciple.html)
  and have different representations for one model.
* Speed. It is one of the fastest data parsing and serialization libraries.
* There is no forced model representation, adaptix can adjust to your needs.
* Support [dozens](https://adaptix.readthedocs.io/en/latest/specific_types_behavior.html) of types,
  including different model kinds:
  ``@dataclass``, ``TypedDict``, ``NamedTuple``, and [``attrs``](https://www.attrs.org/en/stable/)
* Working with self-referenced data types (such as linked lists or trees).
* Saving [path](https://adaptix.readthedocs.io/en/latest/tutorial.html##error-handling)
  where an exception is raised (including unexpected errors).
* Machine-readable [errors](https://adaptix.readthedocs.io/en/latest/tutorial.html#error-handling)
  that could be dumped.
* Support for user-defined generic models.
* Automatic name style conversion (e.g. `snake_case` to `camelCase`).
* [Predicate system](https://adaptix.readthedocs.io/en/latest/tutorial.html#predicate-system)
  that allows to concisely and precisely override some behavior.
* Disabling additional checks to speed up data loading from trusted sources.
* No auto casting by default. The loader does not try to guess value from plenty of input formats.
