Struct WaitableDataChannelSynchronousProxy 

pub struct WaitableDataChannelSynchronousProxy { /* private fields */ }

Implementations

impl WaitableDataChannelSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<WaitableDataChannelEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn read( &self, ___deadline: MonotonicInstant, ) -> Result<WaitableDataChannelReadResult, Error>

The call will return the next datagram to be read from the channel. If there is more data to be read, SIGNAL_READABLE will remain asserted after this call returns. If there is no data to be read, this call will return ZX_ERR_SHOULD_WAIT

pub fn write( &self, payload: &WaitableDataChannelWriteRequest, ___deadline: MonotonicInstant, ) -> Result<WaitableDataChannelWriteResult, Error>

The call will return once the data is fully committed.

If the driver is not ready for a write, it will return ZX_ERR_NO_RESOURCES and the caller should await SIGNAL_WRITABLE to be asserted.
