[WARNING] the following packages contain code that will be rejected by a future version of Rust: bar v1.0.0
[NOTE]
To solve this problem, you can try the following approaches:
- If the issue is not solved by updating the dependencies, a fix has to be
implemented by those dependencies. You can help with that by notifying the
maintainers of this problem (e.g. by creating a bug report) or by proposing a
fix to the maintainers (e.g. by creating a pull request):
- bar@1.0.0
- Repository: https://example.com/
- Detailed warning command: `cargo report future-incompatibilities --id 1 --package bar@1.0.0`
- If waiting for an upstream fix is not an option, you can use the `[patch]`
section in `Cargo.toml` to use your own version of the dependency. For more
information, see:
https://doc.rust-lang.org/cargo/reference/overriding-dependencies.html#the-patch-section
[NOTE] this report can be shown with `cargo report future-incompatibilities --id 1`
