What are you talking about? You can certainly have memory related errors on an embedded system.... and the lifetime of memory can often be shorter than the full on cycle of the device.... you can use memory within a function that is not needed outside of it, etc.

Borrow checking is unrelated to whether you are on an embedded device or not.

If you need reliability and long uptime in an embedded device, dynamic memory management is shunned because it is detrimental to both. The probability of fatal memory fragmentation from bad allocation patterns is too high.
