pub async fn get_functions(
app: Option<FirebaseApp>,
region_or_domain: Option<&str>,
) -> FunctionsResult<Arc<Functions>>Expand description
Fetches (or lazily creates) a Functions client for the given Firebase app.
Mirrors the modular helper exported from packages/functions/src/api.ts.
Passing region_or_domain allows selecting a different region or custom domain just like the
app.functions('europe-west1') overload in the JavaScript SDK.
