Example Code

from typer import Typer
from typer import Response
from typer import Option
from typing import Annotated

import core


class Request(BaseModel):
    credentials: Annotated[str, Option(..., help="...")]

class Login:
    def __call__(self: Self, request: Request) -> Response:
        core.login(credentials=request.credentials)
        return Response(exit_code=0)


cli = Typer()
cli.command(
    name="login",
    help="...",
)(Login())

Description

I find the FastAPI interface for json-rpc style apis to be very fluent. Has the team considered making a similar interface available to Typer?
