This error is caused by a recent commit of crossbeam

We will fix this with crossbeam.

[juntao]

Can we fix our dependency to a specific version of crossbeam for now? It may take time for them to release a new version.

[MediosZ]

yes, adding these lines in Cargo.toml will fix this issue temporarily on Linux

[patch.crates-io]
crossbeam-utils = { git = "https://github.com/crossbeam-rs/crossbeam.git", rev="46d0aeb" }
crossbeam-queue = { git = "https://github.com/crossbeam-rs/crossbeam.git", rev="46d0aeb" }
crossbeam-epoch = { git = "https://github.com/crossbeam-rs/crossbeam.git", rev="46d0aeb" }

However, it doesn't work on macOS because libz can not be compiled for wasi.
This can be fixed by editing async_mysql

[juntao]

I mean to change the deps in mysql_async_wasi to fix it at a version of crossbeam that works?

[MediosZ]

Fixing the version of crossbeam doesn't work cause we do not depend on crossbeam-utils directly.
but adding these patches to async_mysql works indeed.

[MediosZ]

Crossbeam has fixed the problem. It should work on linux without any modification.
But for macos, we need to modify async_mysql a bit.

[MediosZ]

It should work for now. @morristai
If there are any other problems, please let us know.

[morristai]

It works now, you guys are awesome!! 💯
