rust warning: unused doc comment

Rust Warning: Unused Doc Comment

The warning "unused doc comment" in Rust typically occurs when a documentation comment is present but not used in the code. This warning is a helpful feature of the Rust compiler that alerts developers to potentially unnecessary or unused documentation comments.

The warning can be addressed by either removing the unused documentation comment or ensuring that the comment is appropriately utilized within the codebase. Keeping the outer unsafe block is what you're going to do if you're following the warning that rustc currently gives [1].

Conclusion

Unused doc comments in Rust can be addressed by either removing them or ensuring their appropriate usage within the codebase.
