define and return custom error types

How to

  • Inherit from HTTPException[T], set __status__, and optionally declare with errors= on endpoints.

Example

from lihil.errors import HTTPException
from lihil import Route

class VioletsAreBlue(HTTPException[str]):
    __status__ = 418

r = Route("/demo")

@r.get(errors=VioletsAreBlue)
async def roses_are_red():
    raise VioletsAreBlue("I am a pythonista")
