Function generate_code_standalone 

pub fn generate_code_standalone(
    secret_key: &[u8; 32],
    counter: u64,
    alphabet_str: Option<&str>,
    code_length: Option<usize>,
    check_position: Option<CheckPosition>,
) -> String

Generate a code with standalone parameters.

This is useful for testing or one-off generation without a .bin file.

Arguments

• secret_key - 32-byte secret key
• counter - Counter value
• alphabet_str - Alphabet string (default if None)
• code_length - Number of random characters (9 default)
• check_position - Check digit position (End default)

Example

use promocrypt_core::{generate_code_standalone, CheckPosition};

let secret = [0u8; 32];
let code = generate_code_standalone(&secret, 0, None, None, None);
assert_eq!(code.len(), 10);
