Handling non-`Send` data in a `Send` closure

The blog post addresses the challenge of using non-`Send` functions in contexts that require `Send` closures in Rust programming. It includes a specific solution that involves wrapping these functions to convert their return types to be `Send`. However, the Rust compiler presents issues, which the author discusses. They seek clarity on whether the code can be adjusted to work correctly and inquire about the need for unsafe code in this context.
