Type Alias async_wait_t 

pub type async_wait_t = async_wait;

Holds context for an asynchronous wait operation and its handler.

After successfully beginning the wait, the client is responsible for retaining the structure in memory (and unmodified) until the wait’s handler runs, the wait is successfully canceled, or the dispatcher shuts down. Thereafter, the wait may be started begun or destroyed.
