parse JSON and form data bodies

How to

• JSON: declare a structured type (e.g., msgspec.Struct or Payload) as a parameter; Lihil parses and validates.
• Form: use Annotated[T, Form()] and UploadFile for file parts.

Examples

from msgspec import Struct
from lihil import Route

class User(Struct):
    name: str

users = Route("/users")

@users.post
async def create_user(user: User) -> User:
    return user

from typing import Annotated
from lihil import Route, Form, UploadFile

upload = Route("/upload")

@upload.post
async def upload_avatar(file: UploadFile) -> str:
    return file.filename

@upload.post
async def upload_many(
    files: Annotated[list[UploadFile], Form(max_files=5)]
) -> int:
    return len(files)
