Struct corona::errors::Dropped
[−]
[src]
pub struct Dropped;
An error marker when a future is dropped before having change to get resolved.
If you wait on a future and the corresponding executor gets destroyed before the future has a chance to run, this error is returned as there's no chance the future will ever get resolved. It is up to the waiter to clean up the stack, or use methods that panic implicitly.
