Struct WaitableDataChannelProxy 

pub struct WaitableDataChannelProxy { /* private fields */ }

Implementations

impl WaitableDataChannelProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.hardware.google.nanohub/WaitableDataChannel.

pub fn take_event_stream(&self) -> WaitableDataChannelEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn read( &self, ) -> QueryResponseFut<WaitableDataChannelReadResult, DefaultFuchsiaResourceDialect>

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, ) -> QueryResponseFut<WaitableDataChannelWriteResult, DefaultFuchsiaResourceDialect>

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.
