Serde Pickle Serialization Library

This is a fork of https://crates.io/crates/serde-pickle with support for recursive data structures and variantly support for Value types to make working with pickled data easier.

THIS CRATE IS NOT INTENDED FOR WIDE USE, AND I MAKE NO GUARANTEES ABOUT BEING A GOOD PROJECT MAINTAINER (although I will not be evil, I just cannot guarantee that I can support this crate)

Documentation

This crate is a Rust library for parsing and generating Python pickle streams. It is built upon Serde, a high performance generic serialization framework.

Installation

This crate works with Cargo and can be found on crates.io with a Cargo.toml like:

[dependencies]
serde = "1.0"
pickled = "1.0"

Requirements

Minimum supported Rust version is 1.41.1.

Usage

As with other serde serialization implementations, this library provides toplevel functions for simple en/decoding of supported objects.

Example:

use std::collections::BTreeMap;

fn main() {
    let mut map = BTreeMap::new();
    map.insert("x".to_string(), 1.0);
    map.insert("y".to_string(), 2.0);

    // Serialize the map into a pickle stream.
    // The second argument are serialization options.
    let serialized = pickled::to_vec(&map, Default::default()).unwrap();

    // Deserialize the pickle stream back into a map.
    // Because we compare it to the original `map` below, Rust infers
    // the type of `deserialized` and lets serde work its magic.
    // The second argument are additional deserialization options.
    let deserialized = pickled::from_slice(&serialized, Default::default()).unwrap();
    assert_eq!(map, deserialized);
}

Serializing and deserializing structs and enums that implement the serde-provided traits is supported, and works analogous to other crates (using serde_derive).
