Expand description

If debug assertions are enabled, asserts two values are not equal, returning otherwise.

Non-panicking version of debug_assert_ne.

§Custom return values

Unless otherwise specified, this will return the default value of the return type (if it has one). A custom value can be returned instead by supplying it as an additional argument (similar to assert’s custom message), i.e. soft_debug_assert_ne!(2 + 2, 4, Err(e)). Ownership of the value is only taken if the assertion fails, so you can continue to use them later on.

This does not perform Err(..)-wrapping, to allow returning any value.
