Macro batch_keys 

macro_rules! batch_keys {
    ($key_type:ty => [$($key_str:expr),* $(,)?]) => { ... };
}

Create multiple keys at once with error handling

This macro simplifies the creation of multiple keys from string literals or expressions, with automatic error collection.

Examples

use domain_key::{define_domain, key_type, batch_keys};

define_domain!(UserDomain, "user");
key_type!(UserKey, UserDomain);

// Create multiple keys, collecting any errors
let result = batch_keys!(UserKey => [
    "user_1",
    "user_2",
    "user_3",
]);

match result {
    Ok(keys) => println!("Created {} keys", keys.len()),
    Err(errors) => println!("Failed to create {} keys", errors.len()),
}
