Struct k9::MultilineString

pub struct MultilineString(pub String);

assert_equal! takes a std::fmt::Debug trait object as an argument which doesn’t work well with multiline strings, since newline characters will be displayed as \n For example this string:

let s = "A
B
C";

will be printed as a single line "A\nB\nC", which is not useful for multiline comparison diff

Using this struct makes the original string serialize into a proper multiline string which will produce a nice line by line difference comparison when used together with assert_equal!.

use k9::{MultilineString, assert_equal};

let s1 = "A\nB\nC".to_string();
let s2 = "A\nD\nC";
assert_equal!(MultilineString(s1), MultilineString::new(s2));
