embedded hardware, any processor Rust doesn't support (there are many), and any place where code size is critical. Rust has a BIG base size for an application, uselessly so at this time. I'd also love to see if it offered anything that could be any use in those spaces - especially where no memory allocation takes place at all. C (and to a lesser extent C++) are both very good in those spaces.

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.
