deser-path

Experimental extension library to deser that provides path wrapping.

lib.rs:

This crate provides a wrapper type that observes the serialization to communicate the current path of the serialization into the SerializerState and 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
