In past I’ve asked something like (a more principled variant of) C Variable Length Arrays for Rust, but lately they are removing them all from Linux kernel, so I am not sure it’s a good idea to add them to Rust:    But the slide 8 is suspicious, to me it seems too much added code. So I’ve tried the code myself:  #include <stdio.h> #include <string.h>  void call_me1(char *stuff, int step) {     char buf[10];     strncpy(buf, stuff, sizeof(buf) - 1);     buf[sizeof(buf) - 1] = '\0';     printf("%d...
