tpack-macros

Procedural macros for native schema binding.

This crate generates TpackSerialize and TpackDeserialize implementations from Rust item definitions.

Purpose

• avoid runtime reflection tables
• avoid string-based field lookup in the hot path
• preserve stable field identity through explicit field_id annotations

Example

#[tpack(auto)]
#[derive(TpackSerialize, TpackDeserialize)]
pub struct LogEntry {
    pub timestamp: u64,
    pub message: String,
}

By default, each field must declare #[tpack(field_id = N)]. Add #[tpack(auto)] to opt into declaration-order numbering starting at 1.
