You may be confused about the difference between a standard library and a runtime. Rust has a standard library (which can be disabled in resource-constrained environments) but no runtime - there's nothing to initialize or tear down, code is just executed. Languages like Go, Python etc. have a runtime (which includes for example the garbage collector.)
