This is very similar to the C++std::stringwe showed earlier, except that the elements in the buffer are 32-bit values, not characters. Note that the words holdingpadovan’s pointer, capacity, and length live directly in the stack frame of theprint_padovanfunction; only the vector’s buffer...
", we test ourwrite_stringmethod and the handling of unprintable characters. To see the output, we need to call theprint_somethingfunction from our_startfunction: // in src/main.rs#[unsafe(no_mangle)]pub extern"C"fn_start() ->!{vga_buffer::print_something();loop{}}...
