Boxed Number Slices: Box<[u8]>, Box<[i8]>, Box<[u16]>, Box<[i16]>, Box<[u32]>, Box<[i32]>, Box<[u64]>, Box<[i64]>, Box<[f32]>, and Box<[f64]>

T parameter	&T parameter	&mut T parameter	T return value	Option<T> parameter	Option<T> return value	JavaScript representation
Yes	No	No	Yes	Yes	Yes	A JavaScript TypedArray of the appropriate type (Int32Array, Uint8Array, etc...)

Note that the contents of the slice are copied into the JavaScript TypedArray from the Wasm linear memory when returning a boxed slice to JavaScript, and vice versa when receiving a JavaScript TypedArray as a boxed slice in Rust.
