Topic: ✔ Discrepancy between Instrument an Operation

Hey all -- I'm working on updating jco (in particular to support the recent semver @since/@after changes) with the latest (unreleased IIRC)wasmtime-environ changes, I've run into an interesting difference:

There's wasm_decoder's Instruction enum

And wasmparser's Operator enum

Now they're obviously the same except for using tuple variants vs struct variants... except for the fact that wasm_encoder::Function::instruction takes only Instructions...

Is there a way to go in between these two obviously-identical types, or should I write some new code to go between? I'm pretty sure the types match up, and there are only so many that actually have associated data... But feels like I might be missing something.

⚠️ DO NOT MERGE Still a couple issues left: define_translate macro broken Instruction vs Operation use in wasmparser::for_each_operator! Compiling js-component-bindgen v1.2.4 (/home/user/code/...

This was recently implemented in wasm-tools but hasn't been published yet. The per-operator translation looks like this

I think you want something like this line

Ah thank you for the pointer!

I might see if I can pull in that newer version of wasm-encoder and get away with using it directly!
