Error: failed to parse manifest at `/Users/oherrala/rust/cargo-bom/Cargo.toml`
Caused by:
feature `edition2021` is required
The package requires the Cargo feature called `edition2021`, but that feature is not stabilized in this version of Cargo (1.55.0).
Consider adding `cargo-features = ["edition2021"]` to the top of Cargo.toml (above the [package] table) to tell Cargo you are opting in to use this unstable feature.
See https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#edition-2021 for more information about the status of this feature.
