Summary

Support defining a serialization name on the model type that is applied any time that type is parsed by a DTO factory

Basic Example

from dataclasses import dataclass, field
from typing import Annotated, Any, TypeAlias

from litestar.dto.field import DTOField

AliasedStr: TypeAlias = Annotated[str, DTOField(serialization_name="bar")]

@dataclass
class Message:
    id: str
    foo: AliasedStr

Drawbacks and Impact

Impact should be relatively minor, adds yet another way to rename fields, however the pattern is already established for marking fields private.

Unresolved questions

Should we just bite the bullet and embellish DTOField with every parameter on DTOConfig that makes sense?
