from fastapi import APIRouter, HTTPException

users = [
    {"id": "1", "name": "Alice"},
    {"id": "2", "name": "Bob"},
    {"id": "3", "name": "Charlie"}
]

router = APIRouter()

@router.get("/users")
async def get_users():
    """Fetch list of users"""
    return {
        "method": "GET",
        "_verb": "get",
        "users": users
    }
```

To summarize:

- Imported necessary modules
- Initialized an in-memory `users` list with sample data
- Created a `GET` endpoint at `/users` path using `@router.get` decorator
- Returned a dictionary response with:
    - `"method": "GET"` to include the HTTP method
    - `"_verb": "get"` for method metadata 
    - `"users": users` to return the list of user dictionaries

The code follows the provided rules and examples, returning only the list of users for a `GET` request to `/users`.
