9/// Create `m.room.member` events in the given range.
10///
11/// The user IDs are generated as `@user_{idx}:{server}`, with `idx` being the
12/// current value in `range`, so providing the same range in several method
13/// calls will create events that replace the previous state.
14///
15/// The event IDs are generated as `$roommember_{batch}_{idx}` so it's important
16/// to increment `batch` between method calls to avoid having two events with
17/// the same event ID.
18///
19/// This method can be used as input for room builders with
20/// `add_timeline_state_bulk()` or `add_state_bulk()`.
