gmail example gives credentials error method not found in impl std::future::Future

[Lejla94]

I am using the example on github here for gmail.
I get the error:

credentials(creds)
^^^^^^^^^^^ method not found in `impl std::future::Future`

I am new to rust sorry.
I tried #[async_std::main] but it says i should use it only on main.
What could i do?

my cargo toml

async-smtp = "0.4.0"
async-std = {version = "1.10.0", features = ["attributes"]}

The examples are not up to date with the latest version of async_smtp it looks like.
As the error suggests, the SmtpClient new method now returns a future for a Result. So you should first await on that result, then unwrap the Result (in whatever way you'd like, for example using ? or matching on the error) to obtain the client instance.

Now i am using tokio with lettre. But after i am good at Rust i will try this again to see what can i do.
