Function libmacchina::extra::pop_newline

pub fn pop_newline<T>(string: T) -> String where
    T: ToString, 

This function pops \n from the end of a given String if it is found.

This can come in handy when reading the contents of a file that might contain a newline control character at the end of the line.

Files of this kind are very common on GNU/Linux systems.

Example

use libmacchina::extra::pop_newline;

let a = String::from("Foobar\n");
let b = String::from("Foobar");

assert_eq!(pop_newline(a), b);
