Those aren't tricks. Rust does not choose the same defaults as C, and, among other things, statically links to the stdlib and jemalloc. The tricks you describe

Those aren't tricks. Rust does not choose the same defaults as C, and, among other things, statically links to the stdlib and jemalloc. The tricks you describe are just changing the compile options to those that C uses by default. on top of that you can apply the same tricks as C; e.g. by running strip, truncating the binary, writing a linker script, etc.
