Stdin how to skip first line

help
#1

Hello,

I'm new to Rust and come from JS and TS.

Is there a way to ignore the first line that comes with stdin?

Scenario
My program will get a file piped in, and the first line us no use to me.

#2

Call read_line once.

#3

But that my code would look like this

let mut dont_need_it = String::new();
let _ = std::io::stdin().read_line(&mut dont_need_it);

let mut stuff_i_need = String::new();
let _ = std::io::stdin().read_line(&mut stuff_i_need);
#4

Correct.

#5

Yes. Because stdin doesn't implement Iter trait.

#6

Also you can write:

std::io::stdin().read_line(&mut String::new());
