It seems to be no element of error in Cargo.toml.

My hunch is that this is the same error as
#2689

because you're using edition 2024, which is behind a feature-flag in the nightly version we're currently building with

[kaaatsu32329]

I see. Thank you.

I'll wait for the implementation for edition 2024.

[syphar]

So your library is intentionally nightly-only?

[syphar]

seeing all the reports that need a newer nightly I decided to unfreeze the version.

I also queued rebuilds for the release above

Thank you.
