Trying to use a proc macro from a 2018 edition crate in a 2018 edition crate that reexports wasm bindgen's output failed before this commit with "could not find `wasm_bindgen` in `{{root}}`".
This commit was made with
rg " ::wasm_bindgen::" --files-with-matches | xargs sed -i 's/::wasm_bindgen::/wasm_bindgen::/g'
Official documentation is now available at
https://rustwasm.github.io/docs/wasm-bindgen/, so let's leave this git
repository's documentation purely for our own previewing purposes.
This commit switches strategies for storing `JsValue` from a heap/stack
to just one heap. This mirrors the new strategy for `JsValue` storage
in #1002 and should make multiplexing those strategies at
`wasm-bindgen`-time much easier.
Instead of having one array which acts as a stack for borrowed values
and one array for a heap of borrowed values, only one JS array is used
for storage of JS values now. This makes `getObject` far simpler by
simply being an array access, but it means that cloning an object now
reserves a new slot instead of reference counting it. If the old
reference counting behavior is needed it's thought that `Rc<JsValue>`
can be used in Rust.
The new "heap" has an initial stack pointer which grows downwards, and a
heap which grows upwards. The heap is a singly-linked-list which is
allocated/deallocated from. The stack grows downwards to zero and
presumably starts generating errors once it underflows. An initial stack
size of 32 is chosen as that should encompass all use cases today, but
we can eventually probably add configuration for this!
Note that the heap is initialized to all `null` for the stack and then
the initial JS values (`undefined`, `null`, `true`, `false`) are pushed
onto the heap in reserved locations.
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`.
