1//! Derive macros for [`ddd-toolkit-core`](https://docs.rs/ddd-toolkit-core)'s
2//! value-object-shaped traits: `ValueObject`, `EntityId`, `SecretVo`, and
3//! `EnumVo`. Works alongside `ddd-toolkit-core` directly, or through the
4//! [`ddd-toolkit`](https://docs.rs/ddd-toolkit) facade - see this crate's
5//! README for the full list of supported `#[vo(...)]` attributes.
