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));

Trait Implementations

impl Debug for MultilineString

Make diff to display string as multi-line string

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<MultilineString> for MultilineString

fn eq(&self, other: &MultilineString) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
