This commit leverages two new attributes in the Rust compiler,
`#[wasm_custom_section]` and `#[wasm_import_module]`. These two attributes allow
removing a lot of hacks found in wasm-bindgen and also allows removing the
requirement of `wasm-opt` to remove the unused data sections.
This does require two new nightly features but we already required the
`proc_macro` nightly feature and these will hopefully be stabilized before that
feature!
This'll allow binding multiple signatures of a JS function as well as otherwise
changing the name of the JS function you're calling from the Rust function that
you're defining.
Closes#72
This attribute indicates that methods are to be accessed in a structural method
rather than through their class. This should allow direct access to properties
embedded on objects rather than forcing all objects to have a class/prototype.
Along the way remove the namespace in Rust as this ended up causing too many
problems, alas! The `js_namespace` attribute now almost exclusively modifies the
JS bindings, hence the "js" in the name now.
This commit renames the `static` attribute to `namespace` and simultaneously
reduces and expands the scope. The `namespace` attribute can now be applied to
all imports in addition to functions, and it no longer recognizes full typed
paths but rather just a bare identifier. The `namespace` attribute will generate
a Rust namespace to invoke the item through if one doesn't already exist (aka
bindign a type).
Looks like the recent changes to `Vec::with_capacity` meant that our previous
codegen to avoid panics no longer avoids panics. Let's pick up the `try_reserve`
unstable feature for now and hopefully it'll be stabilized before the other
pieces in the future.
Looks like LLD implicitly pads data values with zeros at the end rather than
explicitly listing them, this means that we need to read out the last byte, even
if it's not 4-byte aligned, as it could still represent a wasm-bindgen-generated
32-bit value.
