I tried this code:

use gstreamer as gst;
use gst::prelude::*;

fn foo(x: gst::Object) {
    let _ = x.get_parent() == Some(x.upcast_ref());
    // let _ = x.get_parent() == Some(x.upcast_ref::<gst::Object>()); // Good error with ::<>
    // let _ = x.get_parent().as_ref() == Some(x.upcast_ref()); // Correct
}

I expected to see this happen:

error[E0308]: mismatched types
 --> src/main.rs:6:36
  |
6 |     let _ = x.get_parent() == Some(x.upcast_ref::<gst::Object>()); // Good error with ::<>
  |                                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ expected struct `gstreamer::Object`, found `&gstreamer::Object`

Instead, this happened:
Either
