| single | # pydantic-core [CI] [Coverage] [pypi] [versions] [license] This package provides the core functionality for [pydantic] validation and serialization. Pydantic-core is currently around 17x faster than pydantic V1. See [`tests/benchmarks/`] for details. ## Example of direct usage _NOTE: You should not need to use pydantic-core directly; instead, use pydantic, which in turn uses pydantic-core._ ```py from pydantic_core import SchemaValidator, ValidationError v = SchemaValidator( { 'type': 'typed-dict', 'fields': { 'name': { 'type': 'typed-dict-field', 'schema': { 'type': 'str', }, }, 'age': { 'type': 'typed-dict-field', 'schema': { 'type': 'int', 'ge': 18, }, }, 'is_developer': { 'type': 'typed-dict-field', 'schema': { 'type': 'default', 'schema': {'type': 'bool'}, 'default': True, }, }, }, } ) r1 = v.validate_python({'name': 'Samuel', 'age': 35}) assert r1 == {'name': 'Samuel', 'age': 35, 'is_developer': True} # pydantic-core can also validate JSON directly r2 = v.validate_json('{"name": "Samuel", "age": 35}') assert r1 == r2 try: v.validate_python({'name': 'Samuel', 'age': 11}) except ValidationError as e: print(e) """ 1 validation error for model age Input should be greater than or equal to 18 [type=greater_than_equal, context={ge: 18}, input_value=11, input_type=int] """ ``` ## Getting Started You'll need rust stable [installed], or rust nightly if you want to generate accurate coverage. With rust and python 3.8+ installed, compiling pydantic-core should be possible with roughly the following: ```bash # clone this repo or your fork git clone git@github.com:pydantic/pydantic-core.git cd pydantic-core # create a new virtual env python3 -m venv env source env/bin/activate # install dependencies and install pydantic-core make install ``` That should be it, the example shown above should now run. You might find it useful to look at [`python/pydantic_core/_pydantic_core.pyi`] and [`python/pydantic_core/core_schema.py`] for more information on the python API, beyond that, [`tests/`] provide a large number of examples of usage. If you want to contribute to pydantic-core, you'll want to use some other make commands: |
