You can absolutely make small rust programs, you just have to actually configure things the right way. Additionally, the Rust language doesn’t have allocation at all, it’s purely a library concern. If you don’t want heap allocations, then don’t include them. It works well.
The smallest binary rustc has produced is like ~145 bytes.
That is far from my only concern. But it's good to see Rust is finally paying attention to binary sizes. And the overwhelming complexity of rust code is definitely not a gain when one is working in embedded spaces anyway. I am however really REALLY annoyed with the aggressive sales tactics of the rust community.

Just to be clear, this isn't a recent development, it has been this way for many years at this point.
