pyserde

Yet another serialization library on top of dataclasses, inspired by serde-rs.

Guide | API Docs | Examples

Overview

Declare a class with pyserde's @serde decorator.

@serde
@dataclass
class Foo:
    i: int
    s: str
    f: float
    b: bool

You can serialize Foo object into JSON.

>>> to_json(Foo(i=10, s='foo', f=100.0, b=True))
'{"i":10,"s":"foo","f":100.0,"b":true}'

You can deserialize JSON into Foo object.

>>> from_json(Foo, '{"i": 10, "s": "foo", "f": 100.0, "b": true}')
Foo(i=10, s='foo', f=100.0, b=True)
