Adding wasm support (feature)

[regular-citizen]

HiGHS is genuinely an impressive piece of software. We use it to power all the coordinate computations for our proof graphical assistant, and it massively outperforms all the pure rust alternatives.

The integration was worth it, but the fact that HiGHS requires a completely different toolchain to compile caused a lot of headaches and required all the above hacks.

Hi, and thanks for opening this !

Is there an advantage to the technique you describe over compiling for the wasm32-unknown-emscripten directly ? Wouldn't it be easier than compiling highs with emscripten separately ?

The reason is that the Rust + web story forces you to compile for wasm32-unknown-unknown. Pretty much every Rust project that compiles to WASM to run in the browser is like this.

See https://rustwasm.github.io/docs/book/reference/add-wasm-support-to-crate.html for more information.

Happy to hear that you've chicaned around this @regular-citizen, but all Greek to me! Great that we've got folk in the rust community to bring HiGHS into play.

Just a note since this issue seems to have an audience: the easiest way to run highs on the web is probably highs-js : https://github.com/lovasoa/highs-js

It's highs compiled to wasm and distributed on npm as a js library
