Crate facet_msgpack 

MsgPack binary format for facet.

This crate provides serialization and deserialization for the MessagePack binary format.

Serialization

use facet::Facet;
use facet_msgpack::to_vec;

#[derive(Facet)]
struct Point { x: i32, y: i32 }

let point = Point { x: 10, y: 20 };
let bytes = to_vec(&point).unwrap();

Deserialization

There are two deserialization functions:

• from_slice: Deserializes into owned types (T: Facet<'static>)
• from_slice_borrowed: Deserializes with zero-copy borrowing from the input buffer

use facet::Facet;
use facet_msgpack::from_slice;

#[derive(Facet, Debug, PartialEq)]
struct Point { x: i32, y: i32 }

// MsgPack encoding of {"x": 10, "y": 20}
let bytes = &[0x82, 0xa1, b'x', 0x0a, 0xa1, b'y', 0x14];
let point: Point = from_slice(bytes).unwrap();
assert_eq!(point.x, 10);
assert_eq!(point.y, 20);

Both functions use Tier-2 JIT for compatible types (when the jit feature is enabled), with automatic fallback to Tier-0 reflection for all other types.

Structs

MsgPackError

MsgPack parsing error.

MsgPackParser

MsgPack parser for deserialization.

MsgPackSerializeError

MsgPack serializer error.

MsgPackSerializer

Functions

from_slice

Deserialize a value from MsgPack bytes into an owned type.

from_slice_borrowed

Deserialize a value from MsgPack bytes, allowing zero-copy borrowing.

to_vec
