rmp-serde 0.14.0

Serde bindings for RMP

This crate connects Rust MessagePack library with serde providing an ability to easily serialize and deserialize both Rust built-in types, the standard library and custom data structures.

Motivating example

extern crate rmp_serde as rmps;

# fn main() {
let buf = rmps::to_vec(&(42, "the Answer")).unwrap();

assert_eq!(
vec![0x92, 0x2a, 0xaa, 0x74, 0x68, 0x65, 0x20, 0x41, 0x6e, 0x73, 0x77, 0x65, 0x72],
buf
);

assert_eq!((42, "the Answer"), rmps::from_read_ref(&buf).unwrap());
# }

Type-based Serialization and Deserialization

Serde provides a mechanism for low boilerplate serialization & deserialization of values to and from MessagePack via the serialization API.

To be able to serialize a piece of data, it must implement the serde::Serialize trait. To be able to deserialize a piece of data, it must implement the serde::Deserialize trait. Serde provides provides an annotation to automatically generate the code for these traits: #[derive(Serialize, Deserialize)].

Examples

extern crate serde;
#[macro_use]
extern crate serde_derive;
extern crate rmp_serde as rmps;

use std::collections::HashMap;
use serde::{Deserialize, Serialize};
use rmps::{Deserializer, Serializer};

#[derive(Debug, PartialEq, Deserialize, Serialize)]
struct Human {
age: u32,
name: String,
}

fn main() {
let mut buf = Vec::new();
let val = Human {
age: 42,
name: "John".into(),
};

val.serialize(&mut Serializer::new(&mut buf)).unwrap();
}
