The connection used between a QRTR client and the QRTR driver.

Variants

Read

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.

Fields

responder: QrtrClientConnectionReadResponder

Write

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.

Fields

dst_node_id: u32

dst_port: u32

data: Vec<u8>

responder: QrtrClientConnectionWriteResponder

GetSignals

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.

Fields

responder: QrtrClientConnectionGetSignalsResponder

GetPortId

Retrieves the port id.

Fields

responder: QrtrClientConnectionGetPortIdResponder

GetNodeId

Retrieves the node id of AP.

Fields

responder: QrtrClientConnectionGetNodeIdResponder

CloseConnection

Close the connection.

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

Fields

responder: QrtrClientConnectionCloseConnectionResponder

#[non_exhaustive]

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: QrtrClientConnectionControlHandle

method_type: MethodType
