Macro assert_all_as_result 

macro_rules! assert_all_as_result {
    ($collection:expr, $predicate:expr $(,)?) => { ... };
}

Assert every element of the iterator matches a predicate.

Pseudocode:
collection into iter ∀ predicate

• If true, return Result Ok(()).

• 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.

This implementation uses ::std::iter::Iterator.
