feature edition2024 is required
The package requires the Cargo feature called edition2024, but that feature is not stabilized in this version of Cargo (1.84.0 (12fe57a9d 2025-04-07)).
Consider trying a more recent nightly release.
See https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#edition-2024 for more information about the status of this feature.
