//! [rmp-serde 1.3](https://crates.io/crates/rmp-serde/1.3.0) ·
//! Enable the `rmp_serde_1_3` feature and
//! [`annotate your type`](crate::native_model) with
//! `native_model::rmp_serde_1_3::RmpSerde` or `native_model::rmp_serde_1_3::RmpSerdeNamed`
//! to have `native_db` use this crate.

/// Used to specify the
/// [rmp-serde 1.3](https://crates.io/crates/rmp-serde/1.3.0)
/// crate for serialization & deserialization, using arrays to serialize structs.
///
/// Do not use this if you plan to use serde features that skip serializing fields,
/// use [RmpSerdeNamed] instead.
///
/// # Basic usage
///
/// After enabling the `rmp_serde_1_3` feature in your `Cargo.toml`, use the
/// [`with`](crate::native_model) attribute on your type to instruct
/// `native_model` to use `RmpSerde` for serialization & deserialization.
///
/// Example usage:
///
/// ```rust
/// # use native_model::*;
/// #[derive(Clone, Default, serde::Deserialize, serde::Serialize)]
/// #[native_model(id = 1, version = 1, with = native_model::rmp_serde_1_3::RmpSerde)]
/// struct MyStruct {
///     my_string: String
