Struct DataChannelProxy

pub struct DataChannelProxy { /* private fields */ }

Implementations

impl DataChannelProxy

pub fn new(channel: AsyncChannel) -> Self

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

pub fn take_event_stream(&self) -> DataChannelEventStream

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

Panics

Panics if the event stream was already taken.

pub fn register( &self, event: Event, ) -> QueryResponseFut<DataChannelRegisterResult, DefaultFuchsiaResourceDialect>

Set event used to signal device state. Discards existing event after having transferred device state to the new event. This must be called before invoking Read or Write, and can fail with ZX_ERR_NO_RESOURCES if the underlying channel is busy.

pub fn get_identifier( &self, ) -> QueryResponseFut<DataChannelGetIdentifierResponse, DefaultFuchsiaResourceDialect>

Returns the identifier associated with this connection.

pub fn read( &self, payload: &DataChannelReadRequest, ) -> QueryResponseFut<DataChannelReadResult, 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.

pub fn write( &self, payload: &DataChannelWriteRequest, ) -> QueryResponseFut<DataChannelWriteResult, 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.

fn is_closed(&self) -> bool

Returns true if the proxy has received the PEER_CLOSED signal.

fn on_closed(&self) -> OnSignals<'_, Unowned<'_, Handle>>

Returns a future that completes when the proxy receives the PEER_CLOSED signal.
