Expand description
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.
