/// The `EventBuilder` struct can be used to easily generate valid sync responses for testing.
/// These can be then fed into either `Client` or `Room`.
///
/// It supports generated a number of canned events, such as a member entering a room, his power
/// level and display name changing and similar. It also supports insertion of custom events in the
/// form of `EventsJson` values.
///
/// **Important** You *must* use the *same* builder when sending multiple sync responses to
/// a single client. Otherwise, the subsequent responses will be *ignored* by the client because
/// the `next_batch` sync token will not be rotated properly.
///
/// # Example usage
///
/// ```rust
/// use matrix_sdk_test::{EventBuilder, EventsJson};
///
/// let mut builder = EventBuilder::new();
///
/// // response1 now contains events that add an example member to the room and change their power
/// // level
/// let response1 = builder
/// .add_room_event(EventsJson::Member)
/// .add_room_event(EventsJson::PowerLevels)
/// .build_sync_response();
///
/// // response2 is now empty (nothing changed)
/// let response2 = builder.build_sync_response();
///
/// // response3 contains a display name change for member example
/// let response3 = builder
/// .add_room_event(EventsJson::MemberNameChange)
/// .build_sync_response();
