Is there a simpler way of checking whether or not an async/await network request is in progress before fetching again without the management of an extra state flag?

e.g.

var isFetching = false

func fetchStuff() {
    guard !isFetching else { return }

    do {
        isFetching = true
        self.stuff = try await getStuff()
    } catch {
        // ...
    }
    isFetching = false
}

Is there a simpler way than using this isFetching flag?
