Asserts that two expressions are not equal to each other.
On panic, this macro will print the values of the expressions with their debug representations.
debug_assert_ne! statements are only enabled in non
optimized builds by default. An optimized build will not execute
debug_assert_ne! statements unless
-C debug-assertions is passed to the
compiler. This makes
debug_assert_ne! useful for checks that are too
expensive to be present in a release build but may be helpful during
development. The result of expanding
debug_assert_ne! is always type checked.
