Rust project goals: Immobile types and guaranteed destructors | Hacker News

A Hacker News post highlights Rust design ideas aimed at improving structured concurrency and async safety.

The main proposals are scoped tasks, immobile types, and guaranteed destructors to strengthen completion and cancellation guarantees.

These traits could bring async closer to scoped threads, making it safer to borrow stack data across tasks.

If adopted, Rust async code could become easier to reason about, especially for cancellation handling and safety.
