Arrr, me hearty! Ye be askin’ for a simple piece o’ code in Rust, peppered with pirate comments. Here be a wee program that prints a hearty greeting:
fn main() {
// Avast, me hearties! We start our voyage here.
let greeting = "Ahoy, matey! Welcome aboard!";
// Yo ho ho! We print our greeting to the open sea!
println!("{}", greeting);
}
Now ye be havin’ a taste o’ pirate-infused Rust code! If ye be havin’ any more requests or need further assistance, feel free to speak up, and I’ll be at yer service!
Obviously programmers are obsolete now. There is no need for us anymore
Arrgh matey, ye be walking ye plank. Ye be sleeping with the fishes down in Davy Jones’ Locker. Yarrrr.
When I compiled that program, the executable was around 10MB. I wrote the same program in C, and the executable was 15kB. That’s about 3 orders of magnitude difference. Is Rust really 1000 times better than C? :-)
Enable LTO, abort on panic, and a higher optimization level and it’ll drop that a ton
set opt level to 3 and enable fat lto.
even without fat lto enabled, my entire multithreaded voxel engine with multithreaded procedural world generation, procedural structures and multiplayer is 5mb in size.I wrote it in C and compiled it for an ATtiny13 and it was 162 bytes. That includes the code to initialize the microcontroller and a bit banged transmit only UART to actually output the text.
The standard lib is statically linked, so there will be a higher baseline binary size. This means that yes, a hello world project may be 10mb unstripped but a considerably more complicated project could in turn be 11mb unstripped. Aka it doesn’t matter much in practice.
