Macro similar_asserts::assert_str_eq

macro_rules! assert_str_eq {
    ($left_label:ident: $left:expr, $right_label:ident: $right:expr $(,)?) => { ... };
    ($left_label:ident: $left:expr, $right_label:ident: $right:expr, $($arg:tt)*) => { ... };
    ($left:expr, $right:expr $(,)?) => { ... };
    ($left:expr, $right:expr, $($arg:tt)*) => { ... };
}

Asserts that two stringified expressions are equal to each other (using PartialEq).

This works similar to assert_eq! but before comparing the values they are stringified via ToString. This also uses a slightly different comparison display that is better optimized for normal strings.

On panic, this macro will print the values of the expressions with their debug representations with a colorized diff of the changes in the debug output.

Like assert!, this macro has a second form, where a custom panic message can be provided.
