The main plugin API structure Plugins export a function that returns a pointer to this struct

Fields

version: u32

API version for compatibility checking

get_metadata: extern "C" fn() -> *const CNodeMetadata

Get metadata about the node type Returns: Pointer to CNodeMetadata (must remain valid for plugin lifetime)

create_instance: extern "C" fn(*const c_char, CLogCallback, *mut c_void) -> CPluginHandle

Create a new plugin instance params: JSON string with initialization parameters (nullable) log_callback: Callback for plugin to send log messages to host log_user_data: Opaque pointer to pass to log callback Returns: Opaque handle to the instance, or null on error

process_packet: extern "C" fn(CPluginHandle, *const c_char, *const CPacket, COutputCallback, *mut c_void, CTelemetryCallback, *mut c_void) -> CResult

Process an incoming packet handle: Plugin instance handle input_pin: Name of the input pin packet: The packet to process output_callback: Callback to send output packets callback_data: User data to pass to output callback telemetry_callback: Callback to emit telemetry events telemetry_user_data: User data to pass to telemetry callback

update_params: extern "C" fn(CPluginHandle, *const c_char) -> CResult

Update runtime parameters handle: Plugin instance handle params: JSON string with new parameters (nullable)

flush: extern "C" fn(CPluginHandle, COutputCallback, *mut c_void, CTelemetryCallback, *mut c_void) -> CResult

Flush any buffered data (called when input stream ends) handle: Plugin instance handle output_callback: Callback to send output packets callback_data: User data to pass to output callback telemetry_callback: Callback to emit telemetry events telemetry_user_data: User data to pass to telemetry callback

destroy_instance: extern "C" fn(CPluginHandle)

Destroy a plugin instance handle: Plugin instance handle
