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!
WASM in WASM!
This directory is an example of using the #[wasm_bindgen] macro to interact
with namespaced APIs like WebAssembly.Module and friends. This example
instantiates a wasm module (from Rust!) and then interacts with it.
You can build the example with:
$ ./build.sh
(or running the commands on Windows manually)
and then opening up index.html in a web browser should show a hello message on
the web page generated by the wasm.
For more information about this example be sure to check out
hello_world which also has more comments about caveats and such.
