This is most likely a duplicate of #668, I believe you should try the workaround that is suggested... Or to try to downgrade your rust version.

@spigaz Thank you for the response

Tried the suggested workaround, but build still fails with this error:

Here's a repo with the current state of things:

I haven't tried the workaround, but other users are downgrading to rust 1.81 for now and say that it works for them.

But I would try it by cloning the workers-rs repository, then updating its references to the git version of wasm-bindgen.

Then in my project I would update it to use the git version of wasm-bindgen and the clone I did of workers-rs that references the git version of wasm-bindgen.

Got it. I'm just playing around with this, so can wait a bit.

How long do you reckon it'll take for these changes to get merged and packaged to crates.io so that I can just do the cargo generate step and have everything work as expected?

Should I expect like a week or two or is this blocked on something else that could take months?

[spigaz]

I don't know, there are a lot of people with the same issue, so I'm guessing that as soon as wasm-bindgen releases the next version, someone will open a PR and it will be merged, followed by a release.

If I had to guess, about two weeks.

@saikatdas0790 The latest version of wasm-bindgen was just released:

https://github.com/rustwasm/wasm-bindgen/releases/tag/0.2.96

You can give it a try and report if its okay...

Looks like it's working now. Will play around more and come back if additional difficulties. Thanks for the help ☺️
