hakotauri

Part of HakoDB — embedded Firestore-style document DB in Rust. The engine + C ABI live in hakodb/hakodb; this repo holds the Tauri gateway crate (pairs with hakotaurits).

Tauri gateway commands for HakoDB: exposes the engine (get/set/query/watch/index admin) as binary (MessagePack) Tauri commands for the @hakodb/tauri TypeScript client.

    ])

Use the module path (gateway::hako_exec), not the root re-export: the #[command] wrapper macro resolves through the same module as the function. (The root re-export covers types and direct calls.)

Watch hot path

Subscriptions prebuild a filter plan once (Hako::plan_for_watch) and match per-event bytes with zero decode (Hako::matches_watch) — the same cost as the former in-tree implementation; only the location moved.

Tauri version

tauri 2.11 + tauri-macros 2.6 + tauri-runtime 2.11 — the minor is unpinned on purpose so cargo unifies one tauri version across the SDK and the consumer binary (two tauri versions in one binary means incompatible State/Window types and unregistrable commands). History: 0.2.x pinned =2.10.3/=2.5.5/=2.10.1 because macros 2.6.x emitted a doubled #[macro_export] (E0255) against tauri 2.10.3; that combination no longer exists on the 2.11 line (verified green with macros 2.6.3 + runtime 2.11.3 — the kastoko app line).
