RxSwift/RxCocoa的以下示例代码有什么作用？

我想详细了解

.drive(resultsTableView.rx_itemsWithCellIdentifier("WikipediaSearchCell",
       cellType: WikipediaSearchCell.self)) 
          { (_, viewModel, cell) in
              cell.viewModel = viewModel
          }

来自WikipediaSearchViewController.swift第47-64行.我试图提取参数来查看具体的类型签名,但重写为

    let temp1 = searchBar.rx_text
        .asDriver()
        .throttle(0.3)
        .distinctUntilChanged()
        .flatMapLatest { query in
            API.getSearchResults(query)
                .retry(3)
                .retryOnBecomesReachable([], reachabilityService: ReachabilityService.sharedReachabilityService)
                .startWith([]) // clears results on new search term
                .asDriver(onErrorJustReturn: [])
        }
        .map { results in
            results.map(SearchResultViewModel.init)
    }

    let driveArg1 = resultsTableView.rx_itemsWithCellIdentifier("WikipediaSearchCell", cellType: WikipediaSearchCell.self)
    let driveArg2 = { (_, viewModel: SearchResultViewModel, cell: WikipediaSearchCell) in
        cell.viewModel = viewModel
    }
    temp1.drive(driveArg1, curriedArgument: driveArg2)
        .addDisposableTo(disposeBag)

给

不能使用类型'(String,cellType:UITableViewCell.Type)'的参数列表调用'rx_itemsWithCellIdentifier'

对于driveArg1和

没有更多上下文,表达式的类型是模糊的

对于driveArg2.

的签名drive和rx_itemsWithCellIdentifier有

public func drive(with: Self -> R1 -> R2, curriedArgument: R1) -> R2 {}

public func rx_itemsWithCellIdentifier(cellIdentifier: String, cellType: Cell.Type = Cell.self)(source: O)(configureCell: (Int, S.Generator.Element, Cell) -> Void) -> Disposable {}

但在这一点上,Swift语法对我来说是难以理解的.任何人都可以解释签名和代码中发生的事情吗？
