GCPluginCallbackHandler is a trait that must be implemented by the application to receive callbacks from the plugin.

Required Methods

fn audit_log(&self, log: &CStr)

Called by the plugin to issue an audit log call.

fn system_log(&self, log_level: GCLogLevel, log: &CStr)

Called by the plugin to issue a system log call.

fn get_last_datapoint_value( &self, datapoint_id: GCDatapointID, ) -> Option<GCArc<GCDatapointValue>>

Called by the plugin to get the last value of a datapoint.

fn publish_datapoint_value(&self, dp_value: &GCDatapointValue) -> bool

Called by the plugin to publish a datapoint value.

fn get_ethernet_interface(&self, name: &CStr) -> Option<GCEthernetInterface>

Called by the plugin to retrieve an Ethernet interface configuration by logical name. Returns interface OS name (e.g., “eth0”), or None if not found or not supported.

fn get_serial_interface(&self, name: &CStr) -> Option<GCSerialInterface>

Called by the plugin to retrieve a serial interface configuration by logical name. Returns tuple of (interface_path, baud_rate, parity, stop_bits, data_bits), or None if not found or not supported.

fn store_datapoint_value(&self, dp_value: &GCDatapointValue)

Called by the plugin to store a datapoint value in the timeseries database.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
