I'm curious if it can be done in Rust entirely though. Maybe some assembly instructions are required e.g. for trapping or setting memory fences.

  If it comes to it then Rust has excellent support for inline assembly

    But how well does it play with memory fences?

      You don’t even need inline assembly for those https://doc.rust-lang.org/stable/std/sync/atomic/fn.fence.html https://doc.rust-lang.org/stable/std/sync/atomic/fn.fence.ht...
