[dependabot]

Bumps the rust-dependencies group in /wasm/tuningplayground with 2 updates: wasm-bindgen and music21-rs.

Updates wasm-bindgen from 0.2.121 to 0.2.122

Release notes

Sourced from wasm-bindgen's releases.

0.2.122

Notices

• Threading support now requires -Clink-arg=--export=__heap_base to be set in RUSTFLAGS for nightly toolchains from 2026-05-06 onward, after rust-lang/rust#156174 removed the implicit __heap_base/__data_end exports on wasm* targets. Atomics CI, CLI reference tests, and the nodejs-threads, raytrace-parallel, and wasm-audio-worklet examples have been updated to pass --export=__heap_base explicitly. The flag is backward-compatible with older nightlies.

• -Cpanic=unwind on wasm targets now emits modern (exnref) exception handling by default after rust-lang/rust#156061, and requires Node.js 22.22.3+ (for WebAssembly.JSTag). Legacy EH wasm can still be produced on current nightlies by adding -Cllvm-args=-wasm-use-legacy-eh to RUSTFLAGS; Node.js 20 may be supported with legacy exception handling, with a tracking issue in #5151.

Added

• Implemented TryFromJsValue for Vec<T> where T: TryFromJsValue. A JS value converts when it is a real Array (per Array.isArray) and every element converts via T::try_from_js_value. This composes recursively (Vec<Vec<String>>, Vec<Option<T>>) and works for any T with a TryFromJsValue impl, including primitives, String, JsValue, and JsCast types. Array-likes (objects with length and numeric indices) are intentionally rejected to mirror the static ABI representation used by js_value_vector_from_abi.

• New extends_js_class and extends_js_namespace attributes on exported structs to allow defining the parent js_class name when it has been customized by js_name and the parent's own js_namespace as well in turn. New validation is added at code generation time that will now catch these cases instead of emitting invalid code. Example:

  #[wasm_bindgen(js_name = "Animal", js_namespace = zoo)]
  pub struct AnimalImpl { /* ... */ }
  #[wasm_bindgen(
  extends = AnimalImpl,
  extends_js_class = "Animal",
  extends_js_namespace = zoo,
  )]
  pub struct DogImpl { /* ... */ }

  #5154
