Doesn't seem to be a problem, at least for Rust: https://godbolt.org/z/fToxz3d7a.

Functions with plain arguments and a struct both produce identical assembly output.

Try compiling with optimizations. I think by default this site doesn't add optimization flags.

Here what happens with optimizations: https://godbolt.org/z/G18zd7chP

Look at the registers usages vs stack

Got it! Thanks for the link.

Also worth noting clippy will warn about writing functions with too many arguments for the same reason listed in TFA

If you add a third argument you get different assembly
