Are there any flatpaks of Rust applications?

The SDK is meant to be "as small as makes sense" which generally means 
sharing critical things from a "Safety" perspective. Maybe Rust makes 
sense here as more freedesktop.org projects switch to Rust. But until 
that happens, having rust in the SDK seems unlikely as it would be undue 
burden to maintain (and add extra overhead to every Runtime based on 
org.freedesktop.Sdk).

I haven't looked to see if anyone is bundling Rust yet, but you would 
only need to build (or install from binary packages) as an early step in 
your flatpak-builder manifest. I'd also expect that you'd want to remove 
anything Rust installed as a final cleanup step (except for whatever 
shared libraries may be necessary if Rust does that).

If you happen to come up with a snippet for a flatpak-builder manifest, 
I'd be interested in it to ship Rust with GNOME Builder.
