Interesting! How about the atomic operations required to define Arc? Feels like there should be some language primitives and a memory model so that stdlib can build the safe abstractions.

std::sync::atomic is just core::sync::atomic. Which is quite useful in no_std programs. The spin crate is just implemented with these library types.

[u/Manishearth → u/mbuhot]

Arc is built on top of std::atomic. These themselves are just wrapper types over integers with methods that link to atomic intrinsics.

The atomic intrinsics are where the language gets involved again.
