Hi, I made a somewhat broken migration of a non-thread-safe SPSC to a thread-safe one looking at the SPSC implementation here for guidance. I [came over this part of the...

In the initial implementation, I implemented `Drop` for `Vec` but I implemented it as a `no-op` for `VecView`, thinking that it should only be dropped through `Vec`. This is incorrect,...

After updating `heapless` to 0.8 in my project (as a transitive dependency of `usb-device` 0.3.2), it fails to build with: ``` error[E0599]: no method named `fetch_add` found for struct `AtomicUsize`...

I'm using heapless-0.8.0 with the feature `mpmc_large`. Instances of MpMcQueue with N >= 256 can be constructed and appear to work correctly, but I think I found an edge case:...

Implement Borrow for Vec and String

1

This would enable using `String` as a key in one of the map or set types in this crate. I see no reason as to why that would not be...

It could very well implement it, since there is already [`IterMut`](https://docs.rs/heapless/latest/heapless/struct.LinearMap.html#method.iter_mut)

The `MpMcQueue`  drop implementation is not optimized, as it uses the normal `dequeue` method, which assumes a shared reference and prevents race condition. `drop` gives us a mutable reference, which...
