Struct fidl_fuchsia_hardware_network::SessionProxy

pub struct SessionProxy { /* private fields */ }

Implementations

impl SessionProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.hardware.network/Session.

pub fn take_event_stream(&self) -> SessionEventStream

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

Panics

Panics if the event stream was already taken.

pub fn attach( &self, port: &PortId, rx_frames: &[FrameType] ) -> QueryResponseFut<SessionAttachResult>

Attaches the session to port.

Once attached, the session starts to receive the subscribed frames over the data FIFOs and it may send frames destined to the specified port.

• request port port to subscribe to.
• request rx_frames Frame types of interest on the port.

• error ZX_ERR_NOT_FOUND if port is not valid.
• error ZX_ERR_INVALID_ARGS if rx_frames is not a subset of the port’s supported frames.
• error ZX_ERR_ALREADY_BOUND if port is already attached.

pub fn detach(&self, port: &PortId) -> QueryResponseFut<SessionDetachResult>

Detaches the session from port.

Once detached, the session stops receiving frames from port. Frames sent to a detached port may be returned with an error. It is not necessary to call Detach on ports that are removed from the device, doing so causes ZX_ERR_NOT_FOUND to be returned.

• request port port to subscribe to.

• error ZX_ERR_NOT_FOUND if the session is not currently attached to the port.

pub fn close(&self) -> Result<(), Error>

Cleanly closes a session.

This will cause the session to send a ZX_ERR_CANCELLED epitaph and proceed to close the Session channel. Clients may only assume that they own all the buffers that are currently owned by the session (sent over either the rx or tx FIFOs) once the epitaph is received. Closing the rx or tx FIFO is equivalent to calling Close.
