* 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
This commit aims to address #1348 via a number of strategies:
* Documentation is updated to warn about UTF-16 vs UTF-8 problems
between JS and Rust. Notably documenting that `as_string` and handling
of arguments is lossy when there are lone surrogates.
* A `JsString::is_valid_utf16` method was added to test whether
`as_string` is lossless or not.
The intention is that most default behavior of `wasm-bindgen` will
remain, but where necessary bindings will use `JsString` instead of
`str`/`String` and will manually check for `is_valid_utf16` as
necessary. It's also hypothesized that this is relatively rare and not
too performance critical, so an optimized intrinsic for `is_valid_utf16`
is not yet provided.
Closes#1348
Most of the CLI crates were already in the 2018 edition, and it turns
out that one of the macro crates was already in the 2018 edition so we
may as well move everything to the 2018 edition!
Always nice to remove those `extern crate` statements nowadays!
This commit also does a `cargo fmt --all` to make sure we're conforming
with style again.
This allows to significantly speed up iteration over small collections, where string encoding is the primary overhead.
Related to #1386, but works around only this partial case.
For all typed arrays, this commit adds:
* `TypedArray::view(src: &[Type])`
* `TypedArray::copy_to(&self, dst: &mut [Type])`
The `view` function is unsafe because it doesn't provide any guarantees
about lifetimes or mutability. The `copy_to` function is, however, safe.
Closes#811
When we add threads it's not actually valid to have a global cache as
the index is only valid on one thread! Instead let's use a per-thread
cache using `thread_local!` which compiles to basically the same code as
before for single-threaded wasm.
This commit adds support for the `slice` function on all `TypedArray`
instances. The `slice` function is similar to `subarray` except that it
actually copies the data, whereas `subarray` just returns a different
view into data.
This commit is a large-ish scale reorganization of our examples. The
main goal here is to have a dedicated section of the guide for example,
and all examples will be listed there. Each example's `README` is now
just boilerplate pointing at the guide along with a blurb about how to
run it.
Some examples like `math` and `smorgasboard` have been deleted as they
didn't really serve much purpose, and others like `closures` have been
rewritten with `web-sys` instead of hand-bound bindings.
Overall it's hoped that this puts us in a good and consistent state for
our examples, with all of them being described in the guide, excerpts
are in the guide, and they're all relatively idiomatically using
`web-sys`.
