/// Example Usage:
/// ```
/// use bystr::bystr;
///
/// // use it as a function call, get a null-terminated byte array
/// let as_bytes = bystr!("this will be a [24; u8]");
/// println!("{:?}", as_bytes);

/// //
/// // an error will be thrown if len(str) >= len_arg.
/// let defined_length = bystr!(10, "hello");
/// assert_eq!(10, defined_length.len());
