C vs Rust

C:
int main(int argc, char **argv) {
int r;
if(argc > 1) {
r = atoi(argv[1]);
} else {
usage();
exit(EXIT_FAILURE);
}
}

Rust:
fn main() {
let argv: Vec<Result<String,OsString>> = std::env::args()
.map(|x| x.into_string())
.collect();

let r = match argv.get(1) {
Some(x) => match x.parse::<i32>() {
Ok(v) => v,
Err(_) => {
show_usage();
panic!()
},
},
None => {
show_usage();
panic!()
}
}
}

Type explosion is to be expected. Do notation could have been used to keep the control logic as clean as C, but Rust is not HASKAL and never will be anything like HASKAL and you're an asshole for wanting to write readable code you filthy shit fuck.
