pub fn recover<P: AsRef<Path>>(base: P) -> Result<()>Expand description
Recovers a queue using the “with replay” strategy.
It applies the following operations, in this order:
- Unlocks both the sender and receiver side of the queue.
- Guesses the position of the receiver using
guess_recv_metadata(this is just the existing state of the receiver most of the time).
This means that some of the data may be replayed, since the receiver
metadata is rarely touched (and it is always a lower bound of where the
receiver actually was). If replays are not acceptable, see
recover_with_loss.
You should also use recover_with_loss if you suppose your data was
corrupted.
Panics
This function panics if there is a file in the queue folder with extension
.q whose name is not an integer, such as foo.q or if the lock files for
either sending or receiving cannot be parsed.
