deser-path

deser 的实验性扩展库，提供了路径包装功能。

lib.rs:

此包提供了一个包装类型，它观察序列化过程，将当前序列化路径通信到 SerializerState 和 DeserializerState。

use deser_path::{Path, PathSerializable};
use deser::ser::{Serialize, SerializerState, Chunk};
use deser::{Atom, Error};

struct MyInt(u32);

impl Serialize for MyInt {
    fn serialize(&self, state: &SerializerState) -> Result<Chunk, Error> {
        // for as long as we're wrapped with the `PathSerializable` we can at
        // any point request the current path from the state.
        let path = state.get::<Path>();
        println!("{:?}", path.segments());
        self.0.serialize(state)
    }
}

let serializable = vec![MyInt(42), MyInt(23)];
let path_serializable = PathSerializable::wrap(&serializable);
// now serialize path_serializable instead
