Struct QrtrClientConnectionSynchronousProxy 

pub struct QrtrClientConnectionSynchronousProxy { /* private fields */ }

Implementations

impl QrtrClientConnectionSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

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

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], ___deadline: MonotonicInstant, ) -> Result<QrtrClientConnectionWriteResult, Error>

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, ___deadline: MonotonicInstant, ) -> Result<EventPair, Error>

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, ___deadline: MonotonicInstant) -> Result<u32, Error>

Retrieves the port id.

pub fn get_node_id(&self, ___deadline: MonotonicInstant) -> Result<u32, Error>

Retrieves the node id of AP.

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

Close the connection.

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