示例1:
// Makes sure that the unwrap call also works when the promise was not yet
// fulfilled, and that the returned Future<T> becomes ready once the promise
// is fulfilled.
TEST(Unwrap, futureNotReady) {
Promise<Future<int>> p;
Future<Future<int>> future = p.getFuture();
Future<int> unwrapped = future.unwrap();
// Sanity - should not be ready before the promise is fulfilled.
ASSERT_FALSE(unwrapped.isReady());
// Fulfill the promise and make sure the unwrapped future is now ready.
p.setValue(makeFuture(5484));
ASSERT_TRUE(unwrapped.isReady());
EXPECT_EQ(5484, unwrapped.value());
}示例2: makeFuture
// Makes sure that unwrap() works when chaning Future's commands.
TEST(Unwrap, chainCommands) {
Future<Future<int>> future = makeFuture(makeFuture(5484));
auto unwrapped = future.unwrap().then([](int i){ return i; });
EXPECT_EQ(5484, unwrapped.value());
