[ERROR] cannot migrate src/lib.rs to edition {next}

", next=next))
If you are trying to migrate from the previous edition ({prev}), the
process requires following these steps:
1. Start with `edition = \"{prev}\"` in `Cargo.toml`
2. Run `cargo fix --edition`
3. Modify `Cargo.toml` to set `edition = \"{latest_stable}\"`
4. Run `cargo build` or `cargo test` to verify the fixes worked
