emscripten-functions-sys

This crate contains bindgen-generated bindings for the system emscripten functions, as presented in their API reference. The following headers have bindings available:

• emscripten
• html5
• console
• websocket

A little description of the files in this project

The bindings are based on the emscripten headers from a compiled emscripten release, like the ones at https://storage.googleapis.com/webassembly/emscripten-releases-builds/, that are downloaded by emsdk.

The emscripten folder contains the headers taken from the emscripten release (currently at version 4.0.1).

The build_bindings.rs file that can be run with e.g. rust-script creates declarations for the emscripten functions using bindgen.

The build_bindings.sh script does the same thing, and requires the bindgen CLI, obtainable e.g. using cargo install bindgen-cli.

The update_emscripten.sh script updates the headers in the emscripten folder to the latest version from the official docker image. Set the DOCKER variable when running this script to specify a path to your docker. Otherwise docker, then podman will be tried.

The src folder already contains the generated bindings.
