From 8efb545625fbaf03b2526a3dfb10197fcdae7e0a Mon Sep 17 00:00:00 2001 From: David Irvine Date: Thu, 17 Jul 2025 20:35:46 +0100 Subject: [PATCH 1/5] feat(data_map): add backward compatibility for serialization MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add support for deserializing old DataMap format (tuple struct) while maintaining the new struct format. This ensures compatibility with existing serialized data in the network. - Add custom Serialize/Deserialize implementations - Support both old array format and new struct format for JSON - Add version byte (1) to binary format for future compatibility - Add to_bytes/from_bytes helpers for bincode with fallback - Add comprehensive tests for backward compatibility BREAKING CHANGE: Binary format now includes version byte. Old binary data can still be read via from_bytes() method. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- Cargo.toml | 1 + src/data_map.rs | 313 +++++++++++++++++++++++++++++++++++++++++++++++- 2 files changed, 311 insertions(+), 3 deletions(-) diff --git a/Cargo.toml b/Cargo.toml index d5dd1bd39..0096fbdad 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -55,6 +55,7 @@ features = ["rt"] criterion = "0.5.1" docopt = "~0.9.0" clap = { version = "4.4", features = ["derive"] } +serde_json = "1.0" [dev-dependencies.tokio] version = "1.34.0" diff --git a/src/data_map.rs b/src/data_map.rs index bcb5f3a66..b6b4f6c39 100644 --- a/src/data_map.rs +++ b/src/data_map.rs @@ -6,15 +6,19 @@ // KIND, either express or implied.
