arkhe-macros

L0 derive macros for arkhe-kernel.

Three procedural derives, one shared shape. Pair the derive with serde::{Serialize, Deserialize}; the kernel provides canonical postcard encoding by default.

Layer

Companion proc-macro crate for the L0 kernel. Not intended for direct use outside of kernel consumers — the derives resolve paths inside ::arkhe_kernel::state::traits::*.

Derives

#[derive(ArkheAction)] — emits Sealed + ActionDeriv. Pair with a hand-written impl ActionCompute for T; the kernel supplies the canonical_bytes / from_bytes / approx_size blanket.
#[derive(ArkheComponent)] — emits Sealed + Component. No user method required beyond serde derives.
#[derive(ArkheEvent)] — same shape as Component; requires Debug + serde.

Every derive expects #[arkhe(type_code = N, schema_version = M)]. schema_version defaults to 1; type_code is mandatory.

Quick start

use arkhe_kernel::{ArkheComponent, ArkheEvent};
use serde::{Serialize, Deserialize};

#[derive(Serialize, Deserialize, ArkheComponent)]
#[arkhe(type_code = 5001, schema_version = 1)]
struct CounterComponent { value: u64 }

#[derive(Debug, Serialize, Deserialize, ArkheEvent)]
#[arkhe(type_code = 8001)]
struct PostCreatedEvent { author: u64, body: String }
