| ## [Unreleased] |
| |
| |
| ## [0.1.6] - 2023-09-14 |
| ### Added |
| * Add `into_raw` and `from_raw` methods on both `Sender` and `Receiver`. Allows passing `oneshot` |
| channels over FFI without an extra layer of heap allocation. |
| |
| |
| ## [0.1.5] - 2022-09-01 |
| ### Fixed |
| - Handle the UNPARKING state correctly in all recv methods. `try_recv` will now not panic |
| if used on a `Receiver` that is being unparked from an async wait. The other `recv` methods |
| will still panic (as they should), but with a better error message. |
| |
| |
| ## [0.1.4] - 2022-08-30 |
| ### Changed |
| - Upgrade to Rust edition 2021. Also increases the MSRV to Rust 1.60. |
| - Add null-pointer optimization to `Sender`, `Receiver` and `SendError`. |
| This reduces the call stack size of Sender::send and it makes |
| `Option<Sender>` and `Option<Receiver>` pointer sized (#18). |
| - Relax the memory ordering of all atomic operations from `SeqCst` to the most appropriate |
| lower ordering (#17 + #20). |
| |
| ### Fixed |
| - Fix undefined behavior due to multiple mutable references to the same channel instance (#18). |
| - Fix race condition that could happen during unparking of a receiving `Receiver` (#17 + #20). |
| |
| |
| ## [0.1.3] - 2021-11-23 |
| ### Fixed |
| - Keep the *last* `Waker` in `Future::poll`, not the *first* one. Stops breaking the contract |
| on how futures should work. |
| |
| |
| ## [0.1.2] - 2020-08-11 |
| ### Fixed |
| - Fix unreachable code panic that happened if the `Receiver` of an empty but open channel was |
| polled and then dropped. |
| |
| |
| ## [0.1.1] - 2020-05-10 |
| Initial implementation. Supports basically all the (for now) intended functionality. |
| Sender is as lock-free as I think it can get and the receiver can both do thread blocking |
| and be awaited asynchronously. The receiver also has a wait-free `try_recv` method. |
| |
| The crate has two features. They are activated by default, but the user can opt out of async |
| support as well as usage of libstd (making the crate `no_std` but still requiring liballoc) |
| |
| |
| ## [0.1.0] - 2019-05-30 |
| Name reserved on crate.io by someone other than the author of this crate. |
