+//! [`Annotate your type`](crate::native_model) with
+//! `native_model::rmp_serde_1_3::RmpSerde` to use the rmp-serde 1.3 crate for
+//! serializing & deserializing.
+
+/// Used to specify the [rmp-serde](https://crates.io/crates/rmp-serde/1.3.0)
+/// `1.3` crate for serialization & deserialization.
+///
+/// # Basic usage
+///
+/// Use the [`with`](crate::native_model) attribute on your type to instruct
+/// `native_model` to use `RmpSerde` for serialization & deserialization.
+///
+/// Example:
+///
+/// ```rust
+/// #[native_model(id = 1, version = 1, with = native_model::rmp_serde_1_3::RmpSerde)]
+/// struct MyStruct {
+///     my_string: String
+/// }
+/// ```
