What's Changed

Breaking changes

• pyserde is powered by beartype by @yukinarit in #476

pyserde's strict type check system is overhauled by using beartype - O(1) runtime type checker. all pyserde classes now implicitly implement beartype decorator by default. Passing wrong type of values in constructor raises beartype's validation error.

@serde
class Foo:
    s: str

If you call Foo with wrong type of object, beartype validation error is raised.

>>> foo = Foo(10)
beartype.roar.BeartypeCallHintParamViolation: Method __main__.Foo.__init__() 
parameter s=10 violates type hint <class 'str'>, as int 10 not instance of str.

If you deserialize with wrong value, serde error is raised.

>>> print(from_json(Foo, '{"s": 10}'))
serde.compat.SerdeError: Method __main__.Foo.__init__() 
parameter s=10 violates type hint <class 'str'>, as int 10 not instance of str.

If you want to disable type check, set either serde.disabled or serde.coerce in type_check class attribute.

from serde import serde, disabled

@serde(type_check=disabled)
class Foo:
    s: str
