Macro assert_starts_with_as_result

macro_rules! assert_starts_with_as_result {
    ($whole:expr, $part:expr $(,)?) => { ... };
}

Assert an expression (such as a string) starts with an expression (such as a substring).

Pseudocode:
a.starts_with(b)

• If true, return Result Ok(()).

• Otherwise, return Result Err(message).

This macro provides the same statements as assert_starts_with, 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.
