So, Go is garbage collected and seems to rely on compiler optimizations for optimizing heap allocations to stack allocations (where applicable). Meanwhile, Rust is centered around manual memory management, discourages heap allocation if you can use stack allocation, and even has (or plans to have) a library for choosing different allocators when those give better performance (which should give an inclination of at what level Rust aims for). And it leverages an existing compiler architecture for generating the native code. Your hunch/gut feeling seems to be very off.
