Macro assert_fn_ne_expr_as_result

macro_rules! assert_fn_ne_expr_as_result {
    ($a_function:path, $a_param:expr, $b_expr:expr $(,)?) => { ... };
    ($a_function:path, $b_expr:expr $(,)?) => { ... };
}

Assert a function output is not equal to an expression.

Pseudocode:
function(a) ≠ b

• If true, return Result Ok(()).

• Otherwise, return Result Err with a diagnostic message.

This macro provides the same statements as assert_, except this macro returns a Result, rather than doing a panic.

This macro is useful for runtime checks, such as checking parameters, or sanitizing inputs, or handling different results in different ways.
