Macro assert_fn_err_ne_as_result 

macro_rules! assert_fn_err_ne_as_result {
    ($a_function:path, $a_param:expr, $b_function:path, $b_param:expr $(,)?) => { ... };
    ($a_function:path, $b_function:path) => { ... };
}

Assert a function error is not equal to another.

Pseudocode:
(a_function(a_param) ⇒ Err(a) ⇒ a) ≤ (b_function(b_param) ⇒ Err(b) ⇒ b)

• If true, return Result Ok(a).

• Otherwise, return Result Err(message).

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