//! [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` 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.
|
|
///
|
|
/// # 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
|
|
/// }
|
|
/// ```
