Struct QrtrClientConnectionProxy 

pub struct QrtrClientConnectionProxy { /* private fields */ }

Implementations

impl QrtrClientConnectionProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.hardware.qualcomm.router/QrtrClientConnection.

pub fn take_event_stream(&self) -> QrtrClientConnectionEventStream

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<QrtrClientConnectionReadResult, DefaultFuchsiaResourceDialect>

Reads a QRTR frame via the connection.

Only one read request can be performed at a time.

• src_node_id: Source node ID of the QRTR frame.
• src_port: Source port of the QRTR frame.
• data: QRTR payload.

• Errors:
  • WOULD_BLOCK: Cannot read; should wait in non-blocking mode.
  • ALREADY_PENDING: More than one read operation is pending in blocking mode.
  • INTERNAL_ERROR: Unexpected QRTR error.

pub fn write( &self, dst_node_id: u32, dst_port: u32, data: &[u8], ) -> QueryResponseFut<QrtrClientConnectionWriteResult, DefaultFuchsiaResourceDialect>

Writes a QRTR frame.

Only one write request can be performed at a time.

• Errors:
  • WOULD_BLOCK: Cannot write; should wait in non-blocking mode.
  • ALREADY_PENDING: More than one write operation is pending in blocking mode.
  • REMOTE_NODE_UNAVAILABLE: Target node unavailable.
  • INTERNAL_ERROR: Unexpected QRTR error.

pub fn get_signals( &self, ) -> QueryResponseFut<EventPair, DefaultFuchsiaResourceDialect>

Retrieves the signals eventpair.

• response signals an eventpair that is signalled with SIGNAL_READABLE and SIGNAL_WRITABLE when read and write buffers are available, respectively.

pub fn get_port_id( &self, ) -> QueryResponseFut<u32, DefaultFuchsiaResourceDialect>

Retrieves the port id.

pub fn get_node_id( &self, ) -> QueryResponseFut<u32, DefaultFuchsiaResourceDialect>

Retrieves the node id of AP.

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

Close the connection.

Server end drops its end of the channel after replying. This can be used for synchronous resource release.
