Struct PythonPluginHandle 

pub struct PythonPluginHandle { /* private fields */ }

Loaded-and-validated handle to one Python plugin.

Implementations

impl PythonPluginHandle

pub fn descriptor(&self) -> &'static PythonInterfaceDescriptor

pub fn method_count(&self) -> usize

pub fn call_typed( &self, method_index: usize, input_bincode: &[u8], ) -> Result<Vec<u8>, PythonCallError>

Typed dispatch.

input_bincode is the bincode-encoded args tuple — the same byte payload the cdylib path would receive. We use bincode here only because every other fidius caller does; on the way into Python we pivot through serde_json::Value (so the host’s I: Serialize works for any type the macro accepts).

pub fn call_typed_json( &self, method_index: usize, input_json: &[u8], ) -> Result<Vec<u8>, PythonCallError>

Typed dispatch where the input is already JSON-serialised (the host’s serde_json::to_vec(&input)). Returns JSON bytes the caller serde_json::from_slice::<O> decodes.

pub fn call_streaming_start( &self, method_index: usize, input_json: &[u8], ) -> Result<PythonStream, PythonCallError>

Start a server-streaming call (FIDIUS-I-0026). Calls the method to obtain its iterator/generator and wraps it in a crate::stream::PythonStream the host then pumps. Input is JSON like Self::call_typed_json; streaming methods use the typed (non-raw) path.

pub fn call_raw( &self, method_index: usize, input: &[u8], ) -> Result<Vec<u8>, PythonCallError>

Raw dispatch — pass bytes in, get bytes out, no encoding.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
