MessagePack support for Swim serialization.

Provides a MessagesPack backend for the Swim serialization system. This consists of two parts:

• A function [read_from_msg_pack] that will attempt to deserialize any type that implements [swimos_form::read::StructuralReadable] from a buffer containing MessagePack data.
• The type [MsgPackInterpreter] that implements [swimos_form::write::StructuralWriter] allowing any type that implements [swimos_form::write::StructuralWritable] to be serialized as MessagePack.

Examples

use bytes::{BufMut, BytesMut};
use swimos_form::write::StructuralWritable;
use swimos_msgpack::{read_from_msg_pack, MsgPackInterpreter};

let mut buffer = BytesMut::with_capacity(128);
let data = vec!["first".to_owned(), "second".to_owned(), "third".to_owned()];
let mut writer = (&mut buffer).writer();

let interpreter = MsgPackInterpreter::new(&mut writer);
assert!(data.write_with(interpreter).is_ok());

let mut bytes = buffer.split().freeze();
let restored = read_from_msg_pack::<Vec<String>, _>(&mut bytes);

assert_eq!(restored, Ok(data));
