We don't support variadic args in front, but, luckily for us, `new Function` accepts comma-separated args as a single string as well (see updated JSON test for an example).
- `JsString::from_code_point` - allows to create JS strings using slice of codes in WASM memory.
- `JsString::from_char_code` - same as above, but also uses updated signature with `u16` instead of `u32` (partially helps with #1460 at least for the new binding).
Now that functions and strings work properly with custom typechecks, these custom methods seem obsolete, so I'd recommend to use standard dyn_ref instead.
Constructing boxed primitives was deprecated in #1447.
Some tests have been still using these methods, so this PR either updates them to use newly added {primitive}::from implementations or adds `#[allow(deprecated)]` where necessary.
Treats any object of shape `{ next: function }` as an iterator via new `is_type_of` method. This is consistent with JavaScript iteration protocol which we already respect.
Also fixes a minor issue that `is_function` was unnecessarily called twice (once explicitly and once as part of `dyn_into` which now does the same check).
This commit adds `#[derive(PartialEq, Eq)]` to many types throughout
`js-sys`. These types are basically all based on `Object`, which means
that `Object.is` can be used for `PartialEq` and the `Eq` requirements
are upheld.
The macro has also been updated to internally store the deref target
instead of unconditionally storing `JsValue`, allowing `#[derive]` to
work a bit better in these situations.
* Ensure `PartialEq` is implemented from these types to native Rust types
* Implement `From` between these type and native Rust types
* Deprecated `Number::new` and `Boolean::new` to discourage use of the
object forms, recommending the `from` constructors instead.
Closes#1446
