examples/discover_devices.rs – struct `DiscoveryFilter` is private

[r-bt]

I'm attempting to run examples/discover_devices.rs in my own project. The steps were

1. cargo new [project-name]
2. As per https://github.com/bluez/bluer/issues/43 added the dependencies 2.1 cargo add -F full bluer 2.2 cargo add tokio 2.3 cargo add env_logger 2.4 cargo add futures
3. Copy code from examples/discover_devices.rs into src/main.rs
4. cargo run

However then I get:

error[E0603]: struct `DiscoveryFilter` is private

The full error log is blow:

I wonder is this related to https://github.com/bluez/bluer/issues/90?
