Control.Churro.Transport.MVar.Latest
Description
MVar Transport Instance. New items overwrite the current queued item.
Useful in subscription-like contexts where you don't care about outdated values.
This is surprisingly useful since it doesn't block sources, but also doesn't accumulate items.
WARNING: Don't use if you want to ensure that all produced items are consumed!
