Is there an equivalently easy way to expose a native interface from C to JS as the example in the post? Relatedly, is it as easy to generate a QR code in C as it is in Rust (11 LoC)?

Yes, for most languages. For example, in Zig (https://ziglang.org/documentation/master/#WebAssembly) or in C (https://developer.mozilla.org/en-US/docs/WebAssembly/C_to_Wa...)

Yes, there are plenty of easy to use QR-code libraries available, for pretty much every relevant language. Buffer in, buffer out.

It's that simple in Rust because it's using a library. C also has libraries for generating QR codes: https://github.com/ricmoo/QRCode

(Obviously there are other advantages to Rust)
