async_task

Struct async_task 

Source
#[repr(C)]
pub struct async_task { pub state: async_state_t, pub handler: async_task_handler_t, pub deadline: zx_time_t, }
Expand description

Holds context for a task and its handler.

After successfully posting the task, the client is responsible for retaining the structure in memory (and unmodified) until the task’s handler runs, the task is successfully canceled, or the dispatcher shuts down. Thereafter, the task may be posted again or destroyed.

Fields§

§state: async_state_t

Private state owned by the dispatcher, initialize to zero with |ASYNC_STATE_INIT|.

§handler: async_task_handler_t

The task’s handler function.

§deadline: zx_time_t

The task’s deadline must be expressed in the time base used by the asynchronous dispatcher (usually |ZX_CLOCK_MONOTONIC| except in unit tests). See |async_now()| for details.
