@st.cache_resource for imported function

Using Streamlit
1

Can @st.cache_resource work for a function defined in another module?

All the examples of @st.cache_resource I have seen use the form:

@st.cache_resource
def connect_to_db():
# lots of code here to initialize and configure the database

client=connect_to_db()

Whereas what I really want to do is something like this:

import utils

@st.cache_resource
client=utils.connect_to_db()

Would this work? If not, is there another way to persistently cache ‘client’?

Found this approach, which seems to work so far:

import utils

client = st.cache_resource(utils.connect_to_db)
