Struct FactoryRegistry 

pub struct FactoryRegistry<T: ?Sized> { /* private fields */ }

Registry of Python factory extractors keyed by Python class name.

The label names the factory kind in error messages, for example "message bus factory".

Implementations

impl<T: ?Sized> FactoryRegistry<T>

pub fn new(label: &'static str) -> Self

Creates an empty registry which describes itself with label in error messages.

pub fn register( &self, type_name: String, extractor: FactoryExtractor<T>, ) -> Result<()>

Registers an extractor for a Python factory type name.

Registering the same extractor again succeeds without change, so a Python module initializer can run more than once per process.

Errors

Returns an error if a different extractor is already registered for the type name.

pub fn extract(&self, py: Python<'_>, factory: Py<PyAny>) -> PyResult<Box<T>>

Extracts a Python object into a boxed factory.

Errors

Returns an error if no extractor is registered for the Python type or extraction fails.

Trait Implementations

impl<T: Debug + ?Sized> Debug for FactoryRegistry<T>

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

Formats the value using the given formatter.
