Iterating StreamGenerator yields Unknown type

[woo-cie]

Iterating StreamGenerator in a for loop yields type Unknown.
In the code example, it should yield DocumentSnapshot.

This can be fixed by changing StreamGenerator.__iter__ ’s return type from StreamGenerator to StreamGenerator[T].

python-firestore/google/cloud/firestore_v1/stream_generator.py

Lines 53 to 54 in 4983639

	def __iter__(self) -> StreamGenerator:
	return self

Environment details

• OS type and version: Windows 11
• Python version: 3.9.13
• pip version: uv-pip 0.6.12
• google-cloud-firestore version: 2.21.0

Steps to reproduce

1. Setup environment as above
2. Check the type shown by the IDE

Code example

db: Client

docs = db.collection("some_table").stream()
for doc in docs:
    pass
