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.
Particularly useful in our tests, where we don't have the regular console
logging with post-facto object inspection, and instead need to provide all this
info up front.
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.
This is intended to handle #1458 and #822. These issues stem from
behavior where:
wasm-pack test --node
will actually run both Node.js and browser tests! Two new env vars are
read here, `WASM_BINDGEN_TEST_ONLY_{NODE,WEB}`, which control which
tests are executed by `wasm-bindgen-test-runner`. The intention is that
these will be set by `wasm-pack` to configure which tests are run, and
if test suites are skipped due to the env vars we'll print an
informational message indicating how they can be run.

This commit enables `[NoInterfaceObject]` annotated interfaces in
`web-sys`. The `NoInterfaceObject` attribute means that there's not
actually a JS class for the object, but all of its properties and such
can still be accessed structually and invoked. This should help provide
more bindings for some more common types on the web!
Note that this builds on recent features to ensure that `dyn_into` and
friends always fail for `NoInterfaceObject` objects because they don't
actually have a class.

This commit switches to executing `rustfmt` by default on
`web-sys`-generated bindings. This improves situations like "view
source" in Rustdoc as well as the IDE interactive debugging experience.
This was initially disabled by default because `rustfmt` took so long to
execute, but nowadays `web-sys` is by default much smaller so there's
much less need to avoid running `rustfmt` in fear of it taking too
long.
Closes#1457
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
