mypy support

[zerlok]

Does this lib support simple mypy check?

If it does, what's wrong with the code below? It doesn't pass mypy check

import gino

db = gino.Gino()

class User(db.Model):
    name = db.Column(db.String())

$ poetry run mypy mypy.py 
mypy.py:1: error: Skipping analyzing "gino": module is installed, but missing library stubs or py.typed marker
mypy.py:1: note: See https://mypy.readthedocs.io/en/stable/running_mypy.html#missing-imports
mypy.py:5: error: Name "db.Model" is not defined
Found 2 errors in 1 file (checked 1 source file)

I can understand missing library stubs (line 1), but why line 5 has an error (mypy.py:5: error: Name "db.Model" is not defined) ?
