macro_rules! assert_io_read_to_string_lt_x_as_result {
    ($a_reader:expr, $b_expr:expr $(,)?) => { ... };
}

Assert a ::std::io::Read read_to_string() value is less than an expression.

Pseudocode:
(reader.read_to_string(a_string) ⇒ a_string) < (expr ⇒ b_string)

• If true, return Result Ok(a_string).

• 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.
