Updates the requirements on wasm-bindgen to permit the latest version.

Release notes

Sourced from wasm-bindgen's releases.

0.2.130

Added

• A borrowed number, bool, char or borrowed string crosses by copy, so &f64, &Option<T>, &Nullable<T>, Option<&f64> and Option<&Nullable<T>> are argument types, and an experimental_generic_mono import taking &T accepts T = f64, Option<f64> or Nullable<String>, as std's contains(&T) does. #5436

• Added a rejection type parameter to js_sys::Promise<T, E = JsValue>, mirrored on JsFuture<T, E>, PromiseState<T, E> and PromiseWithResolvers<T, E>. Awaiting a Promise<T, E> yields Result<T, E>, converting the rejection reason as an E the same unchecked way the fulfilled value is converted as a T. Both parameters are covariant under Upcast; catch, then_with_reject and the withResolvers reject function receive an E; all_tuple / all_settled_tuple carry a shared E through; and under js_sys_unstable_apis, Promise::new, Promise::reject and Promise::any are typed on the rejection too, any as AggregateError. The default keeps existing Promise<T> code unchanged. PromiseWithResolvers<T, E> is invariant in both, since its resolve and reject functions take them, and JsFuture<T, E> is UnwindSafe whenever T and E are. #5426

• Added the --js-string-builtins CLI flag, importing static_string constants as JS String Builtins string constants from wasm:js/string-constants instead of defining them in the JS glue. With reference types, static_string constants now occupy fixed externref table slots filled in when the module is instantiated, so cloning and dropping them is free and never calls into JS. #5401

• Added Nullable<T>, re-exported as js_sys::Nullable, for a T | null value at the JS boundary, as Option<T> is for T | undefined, with Option<Nullable<T>> for T | null | undefined. Both are accepted wherever Option<T> is, for every T and in every position: JS null is Nullable::Null and is sent back as null, while undefined into a plain Nullable<T> goes to T's own conversion. A plain Option<T> still reads both undefined and null as None and writes None as undefined; the Option layer of Option<Nullable<T>> treats only undefined as None, since null has to reach the Nullable layer. Option<T> converts from and into Nullable<T>, and JsNullable<T> converts from both and into Option<Nullable<T>> for T: JsGeneric. The API follows Option's, including ok_or, and_then, filter, as_deref, take, replace and IntoIterator, and --cfg wasm_bindgen_unstable_try_trait enables ? on nightly. NullableIntoWasmAbi / NullableFromWasmAbi carry Nullable<T>'s null for every T, and are supertraits of JsStringLike and the js-sys
