Binary Codec for JSON Patch+

The binary codec serializes JSON Patch+ operations directly to MessagePack using the same array shape as the compact codec. It skips any intermediate JSON/compact conversion, resulting in smaller payloads and higher performance.

Features

• Direct MessagePack output – no temporary compact representation
• Full support for first-order JSON Patch, extended and predicate operations (composite predicates not yet implemented)
• Familiar API: Encode / Decode, aligning with the other codecs

Quick Example

import (
    "github.com/kaptinlin/jsonpatch/codec/binary"
    "github.com/kaptinlin/jsonpatch/op"
    "github.com/kaptinlin/jsonpatch/internal"
)

func main() {
    // Build operations
    ops := []internal.Op{
        op.NewAdd([]string{"/", "foo"}, "bar"),
    }

    codec := binary.Codec{}

    // Encode to MessagePack
    data, err := codec.Encode(ops)
    if err != nil {
        panic(err)
    }

    // Decode back to operations
    decoded, err := codec.Decode(data)
    if err != nil {
        panic(err)
    }

    _ = decoded // use decoded operations
}

TIP: Fully round-trip compatible with the json and compact codecs – mix & match freely.
