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!
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? :-)
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.
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.
Enable LTO, abort on panic, and a higher optimization level and it’ll drop that a ton
