/// Multiple values container
///
/// Uses an enum to represent multiple values of different types, providing type-safe storage and access for multiple values.
///
/// # Features
///
/// - Supports collections of multiple basic data types
/// - Provides two sets of APIs for type checking and type conversion
/// - Supports unified access to single and multiple values
/// - Automatic memory management
///
/// # Example
///
/// ```rust,ignore
/// use common_rs::util::value::MultiValues;
///
/// // Create integer multiple values
/// let mut values = MultiValues::Int32(vec![1, 2, 3]);
/// assert_eq!(values.count(), 3);
/// assert_eq!(values.get_first_int32().unwrap(), 1);
///
/// // Get all values
/// let all = values.get_int32s().unwrap();
/// assert_eq!(all, &[1, 2, 3]);
///
/// // Use generic method to add value
/// values.add(4).unwrap();
/// assert_eq!(values.count(), 4);
/// ```
