Struct ShutdownSignal 

Source 
pub struct ShutdownSignal { /* private fields */ }
Expand description

An awaitable construct for signalling shutdown to supervised processes to complete work and exit on the next available await point Lazily instantiates the future when the future is first polled to allow cloning the underlying token and propagating shutdown signals from a single source in a one-to-many relationship
