## Summary - Upgrades `@napi-rs/cli` from v2 to v3, `napi`/`napi-derive` Rust crates to 3.x - Fixes a bug ([napi-rs#1170](https://github.com/napi-rs/napi-rs/issues/1170)) where the CLI failed to locate the built `.node` binary when a custom Cargo target directory is set (via `config.toml`) ## Changes **package.json / CLI**: - `napi.name` → `napi.binaryName`, `napi.triples` → `napi.targets` - Removed `--no-const-enum` flag and fixed output dir arg - `napi universal` → `napi universalize` **Rust API migration**: - `#[napi::module_init]` → `#[napi_derive::module_init]` - `napi::JsObject` → `Object`, `.get::<_, T>()` → `.get::<T>()` - `ErrorStrategy` removed; `ThreadsafeFunction` now takes an explicit `Return` type with `CalleeHandled = false` const generic - `JsFunction` + `create_threadsafe_function` replaced by typed `Function<Args, Return>` + `build_threadsafe_function().build()` - `RerankerCallbacks` struct removed (`Function<'env,...>` can't be stored in structs); `VectorQuery::rerank` now accepts the function directly - `ClassInstance::clone()` now returns `ClassInstance`, fixed with explicit deref - `Vec<u8>` in `#[napi(object)]` now maps to `Array<number>` in v3; changed to `Buffer` to preserve the TypeScript `Buffer` type **TypeScript**: - `inner.rerank({ rerankHybrid: async (_, args) => ... })` → `inner.rerank(async (args) => ...)` - Header provider callback wrapped in `async` to match stricter typed constructor signature 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>
