Bump wasm-bindgen from 0.2.106 to 0.2.109

[dependabot]

Bumps wasm-bindgen from 0.2.106 to 0.2.109.

Release notes

Sourced from wasm-bindgen's releases.

0.2.109

Added

• Added support for erasable generic type parameters on imported JavaScript types, using sound type erasure in JS bindgen boundary. Includes updated js-sys bindings with generic implementations for many standard JS types and functions including Array<T>, Promise<T>, Map<K, V>, Iterator<T>, and more. #4876

• Added ScopedClosure<'a, T> as a unified closure type with lifetime parameter. ScopedClosure::borrow(&f) (for immutable Fn) and ScopedClosure::borrow_mut(&mut f) (for mutable FnMut) create borrowed closures that can capture non-'static references, ideal for immediate/synchronous JS callbacks. Closure<T> is now a type alias for ScopedClosure<'static, T>, maintaining backwards compatibility. Also added IntoWasmAbi implementation for Closure<T> enabling pass-by-value ownership transfer to JavaScript.

• Added ImmediateClosure<'a, T> as a lightweight, unwind-safe replacement for &dyn FnMut in immediate/synchronous callbacks. Unlike ScopedClosure, it has no JS call on creation, no JS call on drop, and no GC overhead—the same ABI as &dyn FnMut but with panic safety. Use ImmediateClosure::new(&f) for immutable Fn closures (easier to satisfy unwind safety) or ImmediateClosure::new_mut(&mut f) for mutable FnMut closures. Closure parameter types are automatically inferred from context. Also implements From<&ImmediateClosure<T>> for ScopedClosure<T> for API migration. #4950

• Implement #[wasm_bindgen(catch)] exception handling directly in Wasm using WebAssembly.JSTag when Wasm exception handling is available. This generates smaller and faster code by avoiding JavaScript handleError wrapper functions. #4942

• Add Node.js worker_threads support for atomics builds. When targeting Node.js with atomics enabled, wasm-bindgen now generates initSync({ module, memory, thread_stack_size }) and __wbg_get_imports(memory) functions that allow worker threads to initialize with a shared WebAssembly.Memory and pre-compiled module. Auto-initialization occurs only on the main thread for backwards compatibility.

• Added a panic message when a getter has more than one argument. #4936

• Added support for WebIDL namespace attributes in wasm-bindgen-webidl. This enables APIs like the CSS Custom Highlight API which adds the highlights attribute to the CSS namespace. #4930

• Added stable ShowPopoverOptions dictionary and show_popover_with_options() method to HtmlElement, and unstable TogglePopoverOptions dictionary per the WHATWG HTML spec. #4968

• Added unstable Geolocation API types per the latest W3C spec: GeolocationCoordinates, GeolocationPosition, and GeolocationPositionError. The Geolocation interface now has both stable methods (using the old Position/PositionError types with [Throws]) and unstable methods (using the new types without [Throws]}, matching actual browser behavior). #2578

• Added matrixTransform() method to DOMPointReadOnly in web-sys. #4962

• Added the web and node targets to the --experimental-reset-state-function flag. #4909
