Details

Tokio broadcast channel calls clone in parallel, but does not require `Sync` The broadcast channel internally calls `clone` on the stored value when receiving it, and only requires `T:Send`. This means that using the broadcast channel with values that are `Send` but not `Sync` can trigger unsoundness if the `clone` implementation makes use of the value being `!Sync`. Thank you to Austin Bonander for finding and reporting this issue.
