[−][src]Enum task_scope::Canceled
The error type for cancellation.
Variants
The parent task issued a graceful cancellation request. The children are in a "grace period"; The parent will wait until all children complete shutdown.
The parent task is forcibly shutting down children (mainly because the parent is dropped). The children are in a "mercy period"; They can continue execution until the next yield, and then they will be stopped automatically.
