Struct HistoryViewerTimeline

pub struct HistoryViewerTimeline {
    room: OnceCell<Room>,
    state: Cell<LoadingState>,
    has_reached_start: Cell<bool>,
    list: RefCell<Vec<HistoryViewerEvent>>,

}

Fields

room: OnceCell<Room>

The room that this timeline belongs to.

state: Cell<LoadingState>

The loading state of this timeline.

has_reached_start: Cell<bool>

Whether we have reached the start of the timeline.

list: RefCell<Vec<HistoryViewerEvent>>

last_token: RefCell<Option<String>>

model_with_loading_item: OnceCell<FlattenListModel>

A wrapper model with an extra loading item at the end when applicable.

The loading item is a LoadingRow, all other items are HistoryViewerEvents.

loading_item_model: OnceCell<SingleItemListModel>

A model containing a LoadingRow when the timeline is loading.

Implementations
