async_wait

Struct async_wait 

Source
#[repr(C)]
pub struct async_wait { pub state: async_state_t, pub handler: async_wait_handler_t, pub object: zx_handle_t, pub trigger: zx_signals_t, pub options: u32, }
Expand description

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.

Fields§

§state: async_state_t

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

§handler: async_wait_handler_t

The wait’s handler function.

§object: zx_handle_t

The object to wait for signals on.

§trigger: zx_signals_t

The set of signals to wait for.

§options: u32

Wait options, see zx_object_wait_async().
