Rust has scoped threads for this use case. Generally this uses closures as opposed to lifetimes to "bound borrows from above" in a safe way.

Rust has crossbeam, but it is not a complete solution to the problem. Scoped threads were removed.

Would you mind elaborating?

It was removed from the standard library ages ago, but `crossbeam::scope` appears to still be there in the newest release of crossbeam and the git repo.

Using a scope for spawning threads is a solution to a narrow slice of a much larger problem.
