MsgSpec serializers

Fast JSON encoding/decoding for cache values via msgspec.

Install the optional dependency:

pip install dynamic-expressions[serialization-msgspec]

MsgSpecScalarSerializer

Used as the default serializer in Redis cache extensions. Handles JSON-compatible scalars (bool, int, float, str, None, lists, dicts).

dynamic_expressions.serialization.msgspec.MsgSpecScalarSerializer 

from dynamic_expressions.serialization.msgspec import MsgSpecScalarSerializer

serializer = MsgSpecScalarSerializer()
payload = serializer.serialize(True)
assert serializer.deserialize(payload) is True

MsgSpecSerializer

Typed serializer for a specific Python type:

dynamic_expressions.serialization.msgspec.MsgSpecSerializer 

import msgspec
from dynamic_expressions.serialization.msgspec import MsgSpecSerializer


class User(msgspec.Struct):
    name: str
    age: int


serializer = MsgSpecSerializer(instance_of=User)
user = User(name="John", age=30)

payload = serializer.serialize(user)
assert serializer.deserialize(payload) == user

Pass a per-policy serializer on CachePolicy when cached values are not plain scalars.

See the Cache cookbook for Redis integration.
