/// Serde Adapter for Marker-Based Serialization/Deserialization
///
/// `AsSerde` is a wrapper around a type `T` that allows it to be serialized and deserialized
/// using a specific marker type `M`.
///
/// By associating a marker `M` with the wrapped data, `AsSerde` helps to distinguish between
/// different serialization strategies for the same underlying data structure.
///
/// ## Example
///
/// ```
/// # #[cfg(feature = "derive")]
/// # {
/// use serde_many::{AsSerde, DeserializeMany, SerializeMany};
/// use serde::Serialize;
///
/// struct SpecialMarker;
///
/// #[derive(Debug, PartialEq, SerializeMany, DeserializeMany)]
/// #[serde_many(_ = "SpecialMarker")]
/// struct MyData {
///     value: i32,
/// }
/// let my_data = MyData { value: 42 };
/// let wrapped_data = AsSerde::<MyData, SpecialMarker>::new(my_data);
///
/// let serialized = serde_json::to_string(&wrapped_data).unwrap();
/// let my_data = wrapped_data.into_inner();
/// let deserialized = serde_json::from_str::<AsSerde<MyData, SpecialMarker>>(&serialized)
///                     .unwrap()
///                     .into_inner();
/// assert_eq!(my_data, deserialized)
/// # }
/// ```
