Bump wasm-bindgen from 0.2.126 to 0.2.127 - #131

Sourced from wasm-bindgen's releases.

0.2.127

Added

• Navigation API to web-sys #5247

• Added riscv64gc-unknown-linux-gnu release artifacts. #5265

• Added JsNullable<T>, modeling WebIDL nullable types (T | null). Both null and undefined are treated as absent, per WebIDL's ECMAScript conversion rules; the canonical empty value produced from Rust is null. web-sys now uses JsNullable<T> instead of JsOption<T> for nullable types nested inside generics (e.g. Promise<GpuError?> from GPUDevice.popErrorScope()), fixing spec-defined null resolutions being treated as present values under JsOption<T>'s strict undefined-only semantics. JsNullable<T> participates in the same upcast lattice as JsOption<T> (including contravariant closure argument casts), and additionally upcasts from Null and from JsOption<T> itself. Imported extern types now also upcast into JsOption<JsValue> and JsNullable<JsValue>, so catch-all nullable closures can be used where a typed callback is expected. #5234

Changed

• Emscripten output now marks public exports (free functions, classes, enums, and namespace roots) with the __export: true and __force: true symbol attributes on their addToLibrary entries, instead of mutating EXPORTED_FUNCTIONS and pushing to extraLibraryFuncs at library-load time. The $initBindgen init closure is kept via __force: true, and private symbols (including namespace leaves) carry neither attribute — they remain reachable through __deps. Requires an emscripten with __export/__force symbol-attribute support.

• Updated WebGPU bindings to the August 2026 spec, including the new GPUCommandEncoder::copy_buffer_to_buffer overloads and setImmediates. #5246

• Unstable API overload names now elide name tokens shared by every overload variant: LockManager::request_with_callback is now request, and request_with_options_and_callback is now request_with_options. #5246

Fixed

• The name property of the JS error thrown for panic=unwind is now set from a string literal instead of PanicError.name, so it survives minification. #5260

Imported extern types now also upcast into JsOption<JsValue> and JsNullable<JsValue>, so catch-all nullable closures can be used where a typed callback is expected. #5234

• Added experimental JSPI (JS Promise Integration) support: using it emits a compiler warning noting the experimental status. Supports #[wasm_bindgen(jspi)] on exports (sync or async), within which a #[wasm_bindgen(suspending)] import call can suspend to the JS event loop until its Promise settles. js_sys::futures::jspi_block_on_promise also suspends on any Promise inside a synchronous function, while spawn_local is context-aware: tasks spawned from within a JSPI context support synchronous JSPI suspensions throughout their call trees. Compatible with catch (rejections as Err), async, and panic=unwind. #5193

• Added a --ts-typed-array-buffers CLI flag to declare owned typed-array return values (e.g. Vec<u8>) as Uint8Array<ArrayBuffer> in generated TypeScript, since they are always copied into a fresh, non-shared ArrayBuffer. Requires TypeScript 5.7+. #5263
